3. Technical Description
3 Technical Description
3.1 Operating Principle
The VarioCAM® hr is a thermographic system for the long wave infrared spectral range (LWIR) of (7.5 ...
14) µm. The lens images the object scene onto a microbolometer array at a resolution of (640 x 480),
(384 x 288) or (320 x 240) pixels. The electrical signal of the detector arrays is further processed by the
internal electronics. The electronics contains all the functions necessary for camera operation, such as
activation of the microbolometer array, A/D conversion, offset and gain correction, defective pixel
treatment, video and PC interfaces.
There is the choice of operating the system via the integrated membrane keypad at the top and rear of
the thermographic system or by using the joystick at the rear or via optional PC interfaces, available as
RS232* and FireWire (IEEE 1394)*. The use of these interfaces which are available depending on their
versions of equipment requires special software packages. You will find relevant details from Chapter 9
on, Hardware and Software Installation for VarioCAM
®
hr*, page 67.
3.2 Description of the Functional Units
Lens
The camera lens captures the IR radiation emitted by the object in the field of view and images it on the
detector array. Field of view (FOV) and resolution/size of the measuring point (IFOV, Instantaneous Field
of View) are determined at the same distance from the focal length f of the lens used.
The following standard lenses are available:

Detector
The VarioCAM® hr has an uncooled microbolometer FPA detector (uncooled Focal Plane Array). The
detector is thermally stabilised with high precision using a Peltier element and is thus independent of the
ambient temperature.
The various elements of the detector are microscopically minute thin-film resistors on wafer-thin
membranes, which are arranged cantilevered a few micrometers above the silicon read-out circuit. The
thermal radiation of the scene is imaged by the lens of the thermographic system on these detector
elements and absorbed by them. The temperature change of the detector elements resulting therefrom
yields electronically evaluable signals which can be read out line-wise and column-wise by a read-out
circuit.
Applying an uncooled detector guarantees quick availability of the camera function after switching it on
(start-up time < 60 seconds) and long service life (MTTF) in permanent use.
Detector electronics
The detector electronics supplies the BIAS voltages required for detector operation and further control
signals, and it takes care of the pre-processing and digitalisation of the analog video output signal from
the detector.

7.9 Trigger Functionality VarioCAM® high resolution
Triggering only affects the 16-bit data transmission via FireWire. A 14-core system cable transmits the
TTL/CMOS-signal from the interfaces “T1” and “T2” on the Breakout Box to the VarioCAM
included trigger cables in order to connect the Breakout Box, see Fig. 24 and Fig. 27.
■ T1 Trigger channel 1 is used by software IRBIS
®
3.
■ T2 Trigger channel 2 is reserved for SDK and further specific applications.
The voltage level of the VarioCAM
®
hr’s input and output is 5 V TTL/CMOS.
The VarioCAM
®
hr reacts to low-high trigger edges. The trigger event effects a tagging of the FireWire
header index of the next frame (IR image). This tag will be evaluated by the IRBIS
IRBGRAB.DLL, which will then save the respective data. The minimum length of the trigger signal is 10
ns. However, the impulse should not be shorter than approximately 3 ms in order to make for a precise
assignment to the current frame. Nevertheless, a cadence with a duty cycle of 1:1 is also possible.

8.2.4 Spot Editor*
The spot editor is started by pressing the T button for a longer period (TL).
It comprises three states:
■ Spotpos
■ Spotdim
■ Spoteps
These states serve to define and process measurement spots or measurement areas (generally ROI,
Region Of Interest).
An ROI of the resolution of (2 x 2) pixels is defined as a measurement spot. Measurement spots are used
for “punctiform” temperature measurement whereas the result is stated as an average of the image
pixels. If the spot is enlarged to become a measurement area, the display of the local minimum and
maximum temperatures in addition to the average is possible. The display of Minimum/Maximum can be
activated via the Menu "Measure" (see page 50, Fig. 99).
The temperature for an ROI can be displayed via the measurement value table displayed in the lower
right corner or directly in the ROI. The respective adjustment must be made in the main menu (Menu
"Image", 8.3.1 Fig. 62, page 37).
Status "Spotpos"
Pressing TL in the live or focus mode at first starts the mode “Spotpos”, in which the position of the
ROI can be altered. Upon the first initialisation of the spot editor, a spot is automatically generated in the
centre of the thermal image.

VarioCAM
hr comes with an optional colour video camera, which serves the human eye to orientate in
the visible spectral range and which can be used for the simultaneous photographic documentation of the
measuring situation.
The field of view, resolution and viewing angle of the video camera will not fully coincide with the thermal
image, since different lenses are used for the two optical channels and, therefore, the optical axes are not
aligned with each other. According to the focussing of the thermal image, the resulting parallax error will
automatically be corrected.
The menu item "CMOS-camera" serves to switch over to the image from the video camera (VIS mode,
status display "VIS"). The VIS image is focused manually with the help of the thumb wheel on the colour
video camera (camera front, see Fig. 2, page 11).
The brightness of the video image is automatically adjusted. In poor lighting conditions, this can result in a
reduced imaging rate of the VIS image. If required, the video lamp* can additionally be switched on by
means of the A button. The T button switches between the colour and black/white display of the VIS
image. VIS images are directly saved in the VIS mode with the help of the S button. The name of the
saved bitmap image is briefly displayed on the lower right. With the C button the VIS mode is exited to go
into “live”.
Please note that the video lamp will remain active upon exiting the status “VIS” if it is not shut down
previously by hitting the A button. This guarantees the VIS image to be saved in optimal lighting and may
also be used for orientation in darkness. For switching the video lamp off (using A), the VIS mode has to
be activated again.
Menu item "Merge"/Merge mode*
Function Merge facilitates the simultaneous viewing of the infrared and of the video images.

8. Operation
When selecting this function, the video image is displayed black/white independently of the setting in the
menu “CMOS-camera” in order to ease the differentiation of the false-colour display of the temperature
distribution. After activating the “Merge” function, the temperature range and the temperature level can be
adjusted by moving the joystick , and , (live mode). After pressing Enter, the focus distance is
changed in the “Merge” mode by , . When focussing, the position of the thermal image to the VIS
image will change in accordance with the set distance (distance-related automatic correction of the
misalignment of the optical axes). The use of this function is recommended for distances from approx. 1
m. Movements , change the transparency of the thermal image in the “Merge” mode, contrary to the
focus mode where they adjust the zoom.
Menu item "Palette"
Fig. 55 Menu item "Image" - "Palette"
In menu item Palette , the palette settings for displaying the temperature distribution in the thermal image
are made. The current allocation of the various colours/grey scales of the false-colour display to the
respective temperatures is set by means of the palette shown on the right of the display (“Colour scale”,
see Fig. 33, page 24). Thereby, the maximum value of the imaged area above and its minimum below the
colour scale serve as an orientation towards the temperature level.
Menu item Palette → Select.. (see Fig. 57) opens a dialogue for selecting the predefined palettes, with
the following selection to be chosen from:
Fig. 56 Colour palettes: VarioCAM, BlackWhite, IronBow, BlueRed, Marked BW, Rainbow

Menu item Palette → Inverse inverts the current palette. If, for example, the BlackWhite palette is
selected, the lower temperatures are displayed in black by default and the higher temperatures in white. If
the "Inverse" function is activated for BlackWhite, the display will be inverted: Now the lower
temperatures are visualised in white and the higher ones in black (see Fig. 58).
Fig. 58 BlackWhite colour scale (left) and its inverted display (right)
Menu item Palette →16 Steps toggles the display between the default colour depth of 256 colours and 16
steps. By activating the "16 Steps" function, only 16 temperature levels will be displayed instead of 256.
Thereby, distinctions in the image beyond the 16 levels will not be visible any more, “summarising” the
scene in 16 “classes” of the same temperature level (see Fig. 59).
Fig. 59 Colour scale 256 colours (left) and 16 colours (right)
The menu item Palette →Logarithmic toggles the display of temperature values between linear and
logarithmic progression. By default, the linear display of temperatures has been selected. Activating this
function facilitates to use a more differentiated resolution for the lower temperature range than for the
higher one. The effects of the logarithmic presentation can be seen in Fig. 60. The linear colour scale is
displayed on the left. The one in the middle shows its logarithmic version. For better visualisation of the
logarithmic grading, the right one shows the same version defined by only 16 colours, clearly showing the
higher colour resolution for the lower temperatures.
Fig. 60 Linear BlackWhite colour scale (left) and its logarithmic presentation (middle) and its
logarithmic presentation in 16 colours (right)
Logarithimic presentation is recommended for scenes of high temperature dynamics where,
independently of large differences between temperature maximum and minimum, a differentiated
presentation in the lower temperature range is of importance, for example, a printed circuit board with a
“hot” component where, apart from T
, temperature differences in the lower display range are also of
Max
interest.
Activation of the functions "Inverse", "16 Steps" or "Logarithmic" is marked by a prefixed checkmark in
front of the respective menu item. The combination of all three options with each other is possible.

filter, a digital low-pass filter of the first order is used.
Via the submenu, choice can be made from among four filter levels "Off", "Weak", "Medium" and
"Strong". Filtering reduces image noise, which in particular visibly improves the image quality of scenes
of a low temperature gradient. The filter setting “Off” or “Weak” should be used for moving objects or the
documentation of fast temperature changes.

If an isotherm already exists, a second one is created by pressing TL. Should more than one isotherm
exist, T will switch to selecting the active isotherm. By using TL, another isotherm can be generated. The
possible number of isotherms depends on the model.
A opens an input dialogue in the isotherm editor, which will facilitate a numerical definition of limits of the
currently displayed isotherm.
Fig. 68 Input window for the numerical definition of isotherms
A defined isotherm always relates to a fixed temperature level and to a fixed temperature range. If, in the live
mode, the temperature scale is changed, the position of the isotherm in the palette will be adjusted
accordingly; however, the temperature limits will remain unchanged.
Menu item "Level/Range.."
Fig. 69 Menu “Image” - "Level/Range.."
The menu item "Level/Range.." starts a dialogue for numerically defining values for the temperature
level and the temperature range (see Fig. 70). The temperature level thereby defines the centre and the
temperature range defines the width of the set imaging area. However, the thermal image is saved
independently of the limits of the imaged area.
Example: At a desired temperature range of 20°C to 30°C, the level needs to be set at 25°C and 10 K for
the range.

8.3.2 Menu "File"
Fig. 71 Menu "File"
Fig. 71 shows the options of the "File" menu. It comprises all functions relating to the file system. The
various items are described in the following sections.
Directory structure of the VarioCAM® hr
With each data storage, the VarioCAM® hr at first automatically generates subdirectories on the SD card,
whose names enable the user to re-access desired files quickly, also with large amounts of data. Files
are always saved in a subdirectory. The name of the subdirectory is generated by means of the current
date, e.g., on 22 June 2007 the directory would be generated by the name of 070622aa. The maximum
number of files to be saved in a directory is limited to 100 in order to avoid the strenuous search in long
lists. Within a directory, the files are consecutively numbered, but, due to their trunk name (2 letters +
month + day, e.g., AA0622xx,) they can always be related to the respective directory. Should a
subdirectory be full (e.g., with file AA062299.irb), the next file would be generated in directory 070622ab
by the file name AB062200. Thus, filenames are consecutively numbered, beginning at 00 through 99
and, contrary to the directory, do not have any indication for the year in their names. Therefore, on one
day and fully exhausting the capacity of automatically generating directories and filenames, a maximum
of 26 x 26 x 100 = 67,600 files can be saved in 676 directories.
Please note that with each and every new start of the thermographic system s as well as with each serial
measurement*, regardless of the contents of previously generated directories, a new subdirectory will be
created. Should additional files (VIS, Audio, Screenshot, Data) be saved as extra files, the number of
possible thermal image files in one directory will reduce accordingly*.

(back) and stopped by Enter. Moving the joystick , also serves to navigate between single images of
an existing recording. It is possible to restart randomly at any position of the recording and to overwrite
already existing recordings. This requires returning to the record mode with the help of T.
The play rate in the play mode determines the rate of display regardless of the recording rate, i.e. a
sequence recorded at 50 Hz is displayed at a play rate of 50 Hz at the same rate as it has been recorded.
A sequence recorded at 1 Hz is displayed at a play rate of 50 Hz at 50 times its rate.
A performs the “Autoimage” function that serves to automatically adjust the temperature level and

"Emissivity..",
Parameters Emissivity and Environmental temperature as well as Path temperature, Transmissivity and
Distance provide for precise temperature measurement, taking into account real measuring conditions,
especially:
■ the surface properties of the object to be measured and the ambient temperature level
■ the transmissivity of the optical channel, the path temperature and distance.
Correct input of the respective correction parameters requires exact knowledge of the real properties of
the object to be measured as well as of ambient conditions and of the measurement setup. The correction
parameters are adopted for the entire image.
The five menu items "Emissivity..", "Env.temp..", "Path temperature..", "Transmissivity.." and

The ambient temperature is the temperature which the thermographic system detects via the more or less
reflecting object to be measured. This temperature is not necessarily equal to the temperature of the
thermographic system itself or that of its immediate environment.
A reduction of the emissivity below 1.00 will result in an effect of the ambient temperature onto the
measured result. Therefore, it must be determined and entered in such a case at any rate.
Example: A low ambient temperature (e.g. cold night sky) makes a reflecting measuring object (e.g.
windows in a house) appear colder to the thermographic system than it actually is. In the thermal image,
windows (of lesser heat insulation) may at first sight appear colder – allegedly better heat-insulated – than
the better insulated facçade.

Menu item "Buttons"
Fig. 114 Menu "Settings" – "Buttons"
Menu item "Buttons" serves to configure which actions shall be performed when hitting buttons A or T.
For this purpose, the options "NUC" and "Autoimage" in the submenu can be activated or deactivated
for A and "LASER on/off" for T. For button C a variety of additional operations is available. An active
option is checkmarked.
Activating the function "LASER on/off" will link the display of 1 (ROI 1), by using T, with the function of
the integrated laser pointer*: T activates or deactivates the laser pointer parallel to switching the ROI on
or off.
Following additional operations are at your disposal for button C:
■ IR-VIS pressing button C allows to switch between IR and VIS picture
■ IR-Merge insertion of IR picture within the VIS picture
■ IR-BGM activates the function "BG storage" (Menu item “BG memory”* - Page 46)
■ Overlay hide and show function of the menu
■ Palette invert. inversion of current colour palette
■ Autosave funct. activates the function "Autosave" (Menu item "Automatic"
■ – Page 56)
"NUC" homogenises the image (NUC: Non Uniformity Correction). When correcting these low
temperature deviations of the detector elements towards each other, which is due to technological
reasons, the live display of the thermal image is briefly interrupted. The correction is performed by the
system itself by changing the device temperature or within a fixed time interval or can be triggered by the
user by hitting A.
The function "Autoimage" serves to automatically adjust the temperature level and range: According to
the current temperature in the scene, the optimal setting of the temperature scale of the false-colour
presentation is selected. This guarantees that all temperatures of the scene are imaged in the thermal
image in colour or grey scales.
The laser pointer eases orientation in the thermal image. By default, it is adjusted to precisely
mark the centre of the thermal image at a distance of 2 m. This corresponds with the position of
Spot 1, unless it has not been shifted in the spot editor.

Menu item "Extra"
Fig. 115 Menu "Settings" - "Extra"
The menu item "Premium" activates image enhancement of the thermal images, for which immediately
prior to saving the data an internal line-up of the detector elements is carried out and special image
filtering for reducing noise is performed. For using Premium saving, the function is to be activated in the
menu and the data are to be saved by SL out of the live mode.
The menu item "ResEnhanc"* (Resolution Enhancement) activates a hardware-based, resolutionimproving recording method. The thermal image is optically scanned several times, whereas, by shifting
the pixel allocation by respectively half the pixel width, the geometric resolution of (384 x 288) is
increased to (768 x 576) or from (640 x 480) to (1,280 x 960) pixels, accordingly (micro-scanning). Using
the Resolution Enhancement function requires the fixed positioning of the thermographic system (tripod)
and only makes sense to be applied to fixed objects to be measured at a constant temperature.
The menu item "DynResEnh"* (Dynamic Resolution Enhancement) activates a software-based image
improvement method. Using this feature requires special analysis tools*.
The menu item “Return Live” is enabled by default. After having activated the focus mode the camera
takes you back to the live mode by default after approx. 10 seconds. If this function is deactivated the
camera stays in focus mode until the menu will be exited by choosing Enter.
Activated functions are respectively checkmarked in the menu.

8. Operation
Available calibration ranges in the VarioCAM® hr are listed in the submenu “Calib” (see Fig. 116) and, by
respectively selecting them, permit toggling between them. The number of calibration ranges is
dependent on the version of equipment. Also after delivery of the thermographic system, the temperature
measurement range can be extended further by hardware extensions and further calibrations of the
system or measuring can be performed using additional lenses.
By activating the item "Autosel Calib"*, the thermographic system will automatically change the
calibration range with respect to the current temperatures of the scene.
The yellow-marked No. of the calibration range shows that, for the currently attached lens, valid
calibration data are available in the thermographic system. Thereby, the type and serial number of the
lens are checked. Should no valid calibration data be available for the attached lens, the system will mark
all available data by shading the No. of the calibration range either light-red (calibration data for similar
type of lens, no accordance with serial number) or dark-red (neither the type of lens nor the serial number
conform to available calibration data). Apart from the No. of the calibration range, also the status window
(above the colour palette) will be shaded light-red or dark-red accordingly. During operation of the
system, this helps visualise at all times if valid calibration data are missing, regardless of having to check
the calibration range in the menu Settings.
Menu item "Automatic"
Fig. 117 Menu "Settings" – "Automatic"
Menu item "Automatic" comprises available automatic functions of the thermographic camera.
Items "Level" or "Range", respectively, serve the automatic adjustment of the thermal image with
respect to the temperature level or temperature range used. The respective menu item is checkmarked if
one of the two functions is active.

The time of starting the recording needs to be entered into the field "Start". As a preset value, the system
provides the current time when calling up the dialogue for entering the parameters for automatic saving.
Regardless of this, any desired start time between 00:00:00 and 23:59:59 can be set. Should the start
time be set before the current time, the recording will immediately start upon activating this function.
"Interval" indicates in which period (hh:mm:ss) a thermal image is to be saved. The shortest possible
interval is 0.5 s. Please note that the minimum recording period is also affected by the files to be saved
(VIS*, Sceenshot) and by the possibly selected saving modes (e.g. Premium/ResEnh*).
Should shorter interval times be required for recording a sequence of thermal images, using the internal realtime memory* (see Menu "File" menu item “BG-memory“) is recommended.
The box "Count" indicates how many thermal images are to be saved/recorded. The maximum possible
number is 99,999 images.
The box "PremiumSnap" indicates if the thermal images are to be saved in Premium mode (see Fig.
115, Menu "Settings" - "Extra") for reducing the noise in these thermal images.
The values in the various input boxes (figures) can be set by moving the joystick and . Using the
joystick and serves to move among the positions in the input boxes. The T button (acting as a tab
key) is used to jump between the various input boxes. Enter saves the sequence settings. The settings
