1 Introduction
The Photon is a long-wavelength (8 – 14 microns) uncooled microbolometer camera designed
for infrared imaging applications that demand absolute minimum size, weight, and power
consumption. It is available with five different lens focal length options:
• 6.3 mm (52° Horizontal Field Of View or HFOV)—only available for Photon 160
• 14.25 mm (46° HFOV)—only available for Photon 320
• 19 mm (36° HFOV)—available for both Photon 320 and Photon 160
• 35 mm (20° HFOV)—only available for Photon 320
• 50 mm (14° HFOV)—only available for Photon 320
• No Lens (Intended for customers who mount their own lens and perform ancillary
Alternate Lens Calibration—See “Software accessories” on page 2-4.)
Figure 1-1: Photon Cameras: L to R: 6.3mm, 14.25mm, 19mm, 35mm, and 50mm lenses
The camera provides ‘power-in, video-out’ capability, which means that one need only apply input
voltage to receive analog video. For those applications demanding more advanced control, the
Photon camera includes a serial interface (RS-232) for transmitting camera commands and
receiving status. In more demanding situations, the Photon camera also provides a digital data
video output via an LVDS serial connection.
The Photon camera is an export controlled item. In order to increase the Camera’s
exportability, a ‘Slow Video’ version of Photon is available. The frame rate is reduced to
approximately 9 Hz. This change allows Photon to be exported without US export license to
most countries. Please contact FLIR for additional information.

3 Basic Operation of the Photon Camera and GUI
3.1 Operation of the Photon camera using the development kit
The Development Kit (or Accessory Kit) is the simplest way to connect to your Photon camera
to provide power and obtain video. It also facilitates serial communication for more advanced
camera command and control via the free downloadable Photon GUI. In this first section, we
will discuss simply applying power and obtaining video output, not serial communication.
Remove the lens cap. (Remember to replace the lens cap when the camera is not in use to
prevent accidental scratching and dust contamination.)
Using the Development Kit’s Interface Cable and I/O Module, plug one end of the Interface
Cable into the mating connector on the back of the camera, as shown below. Connect the other
end of the Interface Cable to the mating connector on the I/O Module labeled CAMERA.
Photon I/O Module
(333-0005-00)
Photon to I/O Module
cable (308-0076-00-02)
To video monitor
To power supply
(206-0001-20)
Attach one end of a standard BNC cable to the video port labeled VIDEO on the I/O Module.
Attach the other end to a compatible video monitor. If your monitor has an RCA input
connector, a BNC to RCA adapter can be used.
Plug the power supply into an electrical outlet. Insert the circular plug at the other end of the
power supply into the power jack labeled POWER on the I/O Module. The camera will take ~2
seconds to produce an image after you apply of power.
You should see an initial splash screen with the FLIR logo displayed, and then live infrared long
wave imaging video will follow! Point the camera in different directions and notice the imagery. If
the video image appears low in contrast, point the camera at a scene with high thermal
contrast such as at a person.

3—Basic Operation of the Photon Camera and GUI Photon User’s Manual
3.2 Remote control of the Photon camera
The Photon camera accommodates advanced camera control through an RS-232 serial
interface. A user can control the camera via this interface by following the Serial Protocol
Communication and command structure requirements of the Electrical Interface Control
Document and their own hardware/software interface. This requires programming skills and a
strong technical background. The user can also use the Photon GUI offered as a free download
from FLIR using a Windows based PC with the standard serial communications and
components provided in the Development Kit. This software provides remote control of various
camera features and modes. The Photon GUI software is compatible with Windows XP
Professional. The PC must have a spare serial communications port.
If your embedded or specialty applications require custom control software, a Software
Developer’s Kit (SDK) is available. Those intending to generate their own custom software are
encouraged to read the remainder of this section regarding the Photon GUI to better
understand the camera modes and parameters.
3.3 Connecting the serial communications interface using the
development kit
You should have successfully operated the camera and obtained live video on a monitor as
described in paragraph 3.1 “Operation of the Photon camera using the development kit” on
page 3-1.
The only additional hardware required for serial communication is a serial cable connected as
shown below.
To PC serial COM port
(RS232)
Attach one end of a standard RS-232 serial port (9-pin) PC cable to the communications port
labeled RS-232 on the I/O Module. Attach other end to the serial port on your PC. This cable
should be a standard RS-232 cable, not a cross-over configured serial cable.

3—Basic Operation of the Photon Camera and GUI Photon User’s Manual
3.5 Connecting the Photon to a PC via the I/O Module
Step 1 Follow the steps shown in paragraph 3.1 “Operation of the Photon camera using the
development kit” on page 3-1 for basic operation of the Photon camera. After verifying
that the camera is producing an image, power-down the camera.
Step 2 You may have done this operation in Section 6. If not, connect one end of a standard
serial cable (user must provide as this is not included with the Photon camera or the
Development Kit) to the 9-pin female DB9 connector on the I/O module labeled ‘RS232’. Do not use a ‘cross-over’ serial cable.
Step 3 Connect the other end of the standard serial cable to an unused serial port on your
computer. These ports may be labeled ‘COM1’ or ‘COM2’.
Step 4 Power on the camera. Assuming the Photon GUI software is already installed on the
PC (see installation instructions above), launch the software by selecting ‘Start,
Programs, Indigo, Photon GUI.
Step 5 When launched, the software attempts to connect with the camera. If the port
settings are wrong, a pop-up window will appear asking you to enter the proper COM
port. Enter the COM port to which the camera is connected.
Note
The Photon User GUI remembers the last COM port that successfully communicated with a
Photon camera and will use that port as the default at start of the application. If the
connected camera is no longer on that port, the port setting pop-up window will appear asking
for you to select the proper port setting.
When successful connected, the ‘About’ tab of the utility should return data similar to
the following. At the bottom of the application window, you should see the ‘Camera
status request completed’ message.

Photon User’s Manual 3—Basic Operation of the Photon Camera and GUI
3.6 Troubleshooting the Photon GUI
If the Photon GUI does not link with the camera, verify the items in the following checklist:
Is the camera properly cabled to the host PC? Verify that you selected the
proper port if it was not detected automatically. Clicking in the lower right of the Photon GUI
window on top of the word COM will bring up a dialog box indicating COM port. Also, try
disconnecting and then re-connecting either the RS-232 serial cable to the PC. If the GUI was
launched before the serial cable was connected, close the GUI, connect the serial cable, then
re-launch the GUI.
Is the port already in use by another application? Shut down any other
applications that may be using the port. Also, multiple instances of the Photon Camera Control
Program can be instantiated using different ports so be sure the camera you are interested in
controlling is actually connected to the physical
Is the Photon camera power on? Verify that the camera is producing an image on a
separate monitor. Also, at camera power up, you can hear two sets of a click-click sound,
separated by about 5 seconds, as the internal shutter performs its on-power-up calibration. If
you don’t hear these sounds, it’s likely the Photon camera is not being powered correctly.
Contact FLIR Customer Support at (805) 964-9797 if you cannot initiate serial communication
with the camera after verifying these items.

improving image quality via a process called flat-field correction (FFC). During FFC, a small
calibration flag (a shutter) rotates in front of the detector array, presenting a uniform
temperature (a flat field) to every detector element. While imaging the flat field, the camera
updates correction coefficients, resulting in a more uniform array output. The video image is
frozen during the entire process, which takes less than a second, and it resumes automatically
thereafter. Repeating the FFC operation often prevents the imagery from appearing “grainy”.
This is especially important when the camera temperature is fluctuating, such as immediately
after turn-on or when ambient temperature is drifting. FFC can be controlled manually at any
time using the Do FFC command. Photon provides two FFC modes:
Automatic: In the Automatic FFC mode, the camera performs FFC whenever its
temperature changes by a specified amount or at the end of a specified period of time
(whichever comes first). When this mode is selected, input windows are available in
the Photon GUI for specifying the temperature change and the number of frames that
trigger automatic FFC. The temperature change is specified in degrees, with valid
values in the range 0 to 100 in 0.1 degree increments. The time period is specified in
frames, with valid values in the range 0 to 30,000 frames.
Note
FLIR recommends using the factory default values for the two automatic-FFC parameters if
possible. These values were selected to maintain a high degree of image quality over all
camera operating conditions.
Manual: In Manual FFC mode, the camera does not perform FFC automatically based
on specified values of temperature change or expired time. The FFC will be performed
when the “Do FFC” button is clicked.
Note
Even with manual FFC mode selected, large camera temperature excursions will cause the
camera to perform the FFC operation, typically at temperature crossings near 0 degrees C
and 40 degrees C.
Photon displays an on-screen symbol called the Flat Field Imminent Symbol prior to performing
an automatic FFC operation. As shown in Figure 3-4, it is the green square in the upper left of
the video output and is displayed nominally 2 seconds prior to the FFC operation. The duration
of the FFC Imminent Symbol can be set using the FFC Warn Time setting in the Analog Video
tab. (paragraph 3.9).

Photon User’s Manual 3—Basic Operation of the Photon Camera and GUI
External Sync Mode: The Photon camera provides the
ability to either accept or output a frame synchronization
signal. This functionality can also be disabled. See the
Appendix for detailed information regarding External
Synchronization.
Disabled: The camera will turn off frame
synchronization.
Slave: The camera will accept a frame synchronization signal on the interface
connector. The camera output will be frozen if the camera is in slave mode and no
external synchronization signal is received.
Master: The camera will output a frame synchronization signal on the interface
connector when configured as a master.
Note
The external sync signal, or trigger, can only be applied via the Samtec 30-Pin Connector.
The external sync signal is not brought out to the 15-pin D-Sub connector.
FPA Temperature Status: The FPA Camera
Temperature automatically displays the camera’s Focal Plane
Array (FPA) temperature.
Operating Mode: The Photon camera will freeze the
frame imaged when Frozen is selected. Live video will cease
and the frozen frame will persist. To return the camera to live
video, select Real-Time video mode.
Save Settings: After using the Photon GUI to change camera modes
and settings to your desired values, use the Save Settings button to store
your current selections as new power-up defaults. The next time the camera
is powered, the Photon camera will remember these saved settings. If you
do not click Save Settings, the changes you make via the Photon GUI will be valid only for the
current session. Cycling power to the camera will revert to the previously saved settings.
Factory Defaults: The Factory Defaults button restores the
camera’s settings to the initial values specified by the manufacturer.
If you want the factory default settings to become the power up defaults,
first click the Factory Defaults button, then click the Save Settings button.
Reset: The Reset button restarts the camera software and is nearly
identical to cycling power.

3—Basic Operation of the Photon Camera and GUI Photon User’s Manual
Test-Pattern: A Test-Pattern mode is provided to verify
camera electronics.
Off: No test-pattern is provided in this mode.
This is the normal mode for viewing thermal imagery.
Ramp: In this ramp mode, the test pattern shown below and in the Color/LUT section
that follows is provided at the analog and digital data channels.
pix(0,0) pix(159,0)
pix(63,102) = 16383
pix(64,102) = 0
Figure 3-5: Ramp test pattern example for 160 x 128 format sensor
(Digital values shown apply to the optional 14-bit digital data stream.)
pix(0,0) pix(323,0)
Figure 3-6: Ramp test pattern example for 320 x 256 format sensor
pix(183,50) = 16383
pix(184,50) = 0
(Digital values shown apply to the optional 14-bit digital data stream.)
Note
The ramp test pattern is intended primarily for verifying the output of the digital data channel.
The pattern will not necessarily look as shown above when displayed on an analog video
monitor, particularly if an AGC mode other than Automatic is selected. The above image is a
horizontal slice of the full displayed image.
