Notes:

This is a 16mm film camera; the film cassette is on the aft side. The given dimensions are just for the camera, though the size excludes its 285mm connectorised cable. In its 199 x 81 x 208 mm case it weighs 2.21kg.

A Camera is used with a Head Up Display to view the symbology overlaid on the outside world as close as possible to the view that the pilot has through the Combiner Glass. The Camera is a training aid to show how accurately the fighter aircraft engages with the target and ultimately can verify the result of a real engagement.

The Camera assembly is usually mounted on top of the HUD, above the Control Panel, directly aft of the Combiner Glass.

 The earliest Cameras used film strip with a replaceable film module and these were quite large and obstructive to the pilot.  However with the advent of diffractive and waveguide optical systems the Combiner acts as part of the optical collimation and is not just a reflector so that the symbology is not focused at the normal location used.  A new solution had to be found and the Camera is instead located forward of the Combiner and the HUD symbology is scan converted and accurately mixed with the Camera video.

Fortunately a solid state Cameras were developed, using a CCD chip, which convert the optical image into electrical video signals for output to an on-board video recorder or transmitter. The new Cameras are also considerably smaller and more reliable.

 The camera electronics incorporate extensive filtering to provide exceptional, noise-free, image quality.
