Abstract : System descriptions of scanning and staring electro-optic sensors with sampled output are developed as follows. Functions representing image formation, detector response, and analog processing of detector output are formulated in the space and time domain. Then the types of sampling permitted by sensor motion, spatial integration of image irradiance, and temporal integration of sensor output are discussed. Next functions representing sensor output sampled in each of these ways are constructed. The relations for a staring sensor describe a temporal sequence of images; those for a scanning sensor represent a single sampled image. Finally, the space and time domain functions are fourier transformed to the spatial-and temporal-frequency domain to complete the system descriptions. The results should be useful for designing electro-optic sensor systems and correcting data for instrumental effects and other experimental conditions. Keywords include: Electro-optic system analysis, Scanning sensors, Staring sensors, Spatial sampling, and Temporal sampling.
