Abstract:

Schottky barrier focal plane arrays have demonstrated superior performance in imagery and sensitivity in cameras deployed on the ground and on airborne platforms. This study determines the feasibility of placing a camera using one of these arrays in space in the space shuttle cargo bay or on the Shuttle Pallet Satellite. The basic operation and performance of platinum silicide Schottky barrier detectors is first discussed. Then a detailed analysis of all of the technical issues involved in constructing a space based Schottky camera are examined at length. Optical performance, cryogenic cooling, image compensation, data recording, system control, host platform restraints, and relevant MIL-SPECs are covered. A preliminary design that meets all of the design criteria is then described. It is concluded that this application is feasible and would be an extremely valuable research tool to investigate infrared properties of objects in space.
