Introduction
The
DAGE-MTI IR-1000
camera system is based upon a
1/2" Interline CCD that produces high-resolution imaging
into the near IR spectrum. The CCD employs a state of the art
microlens design to increase the light gathering capability of
the CCD. The simplistic front panel design of the
IR-1000
control unit allows easy access to the Gain and Black Level
controls that provide a vast adjustment range. A Test switch
provides a stair step pattern for rapid calibration or
troubleshooting of the attached equipment such as a monitor
or frame grabber. The read-out of the sensor can be inhibited
by an external Gate pulse, which allows increased integration
times in low-light level situations.
The flexibility of the
DAGE-MTI IR-1000
camera system
makes it the camera of choice in almost any imaging
situation.

Installation
The
IR-1000
camera head connects directly into the
control unit. Power for the control is supplied by an external
switching supply that is provided. Ensure that a correct AC
power cord is used in accordance with local safety standards.
All power and interconnections to the
IR-1000
camera head
are supplied through the single interface cable. Gating can be
accomplished by simply using the
DAGE-MTI Investigater
to
control the gate time, display and store the image, or by using
a computer with a frame grabber. Figure 1 shows some
typical setups of the
IR-1000.

use the correct cable end at the control unit and head in
order to avoid damage, which could void the warrantee.
Video
This ‘BNC’ connector supplies video output of the
IR-1000
system. The signal is 1Vp-p terminated into 75Ω.
Be careful to avoid double termination of the output video,
which would result in incorrect video levels. Connect to a
monitor, computer or the
DAGE-MTI Investigater
as
required.
NOTE:
Do not use the
VIDEO OUT
connector on the camera
head. This will cause incorrect video levels to be sent to
the control and the signal at the camera head will be
double terminated.
Gate
This ‘BNC’ connector can be used to provide input of a
gate pulse in order to increase the sensitivity by inhibiting the
readout of the CCD's image and allowing light to gather in
the CCD for extended periods of time before readout.

The timing of the External Gate pulse requires that the
pulse occur sometime during the field immediately before the
CCD readout is to be inhibited. Figure 4 shows the
relationship of the CCD transfer to the output video signal.

As long as the gate pulse edges occur before
transfer, the correct timing will occur. Care should be taken
to ensure that the CCD is gated for an even number of fields
