ICI 7640 Thermal Camera

The ICI 7640 is a microbolometer thermal camera (purchased fromĀ Infrared Cameras Incorporated) used by AggieAir to capture thermal imagery. The AggieAir payload software communicates with the camera through USB to tell it when to take a picture. The payload software also logs important inertial data from the UAV, such as position and orientation.

The payload door opens and closes to expose the camera to the ground and to protect it during landing. The door is also used by the thermal camera to do a non-uniformity correction (NUC).
