Paper Abstract

This paper describes a facility developed by SSG, Inc., that is capable of testing optical sensors for out of field of view rejection (OFVR) in the infrared. Included are descriptions of components, laboratory conditions and electronic instrumentation. Also included are measured results of two infrared optical telescopes, performed at this facility. The Air Force Geophysics Laboratory/Space Division Zodiacal Infrared Program (ZIP) telescope and the Air Force Geophysics Laboratory/Naval Research Laboratory Far Infrared Sky Survey Experiment (FIRSSE) telescope measurements are compared to theoretical predictions. A brief description of a stray radiation analysis computer program used to analyze the ZIP telescope design is included. In addition, effects of baffle design on performance of the ZIP telescope are described. A detailed error analysis of measurement techniques is described showing error bounds down to the noise floor of OFVR. Measurement to less than 10-12 OFVR rejection is achieved for sensors with microsteradian field of view.
