Profile: Optical Energy Technologies is a provider of electro-optic system and solar simulators. Our solar simulators include small solar angular sub-tenses for testing of sun sensors, solar panels, and small satellites. Our discrete optical filter radiometer can be configured to view flash transient events, and an optical chopper can be incorporated for slowly varying radiance. The operation of the radiometer is completely computer controlled, & the output data can be presented in various formats. Our earth sensor measures the attitude of the spacecraft relative to its axis, and it includes two additional detectors which are used to correct for earth radiance variation as a function of season, & position in the orbit.
