Abstract

It is desirable to use thermal detectors in spaceborne electro-optical (EO) systems where the required system performance allows their use. Thermal detectors require no cooling, are stable and rugged, have good uniformity, can be made with large active areas and are broad band, spectrally. The Earth Radiation Budget Experiment (ERBE) is a system in which the properties of thermal detectors, in this case thermistor bolometers, are not only acceptable but are also desirable. The application demands sensing of wide band IR radiation and since the measurements are radiometric ones in which small changes in a large background are to be measured, extremely stable, well characterized detectors are required. This Paper discusses the criteria which characterize good detectors and also describes some of the in-process and final tests that were performed to ensure the delivery of detectors meeting system level requirements.
