Paper Abstract

One method of analyzing the effectiveness of a reimaging optical system in rejecting unwanted radiation from out-of-field sources is described. The rejection ratio, the parameter used to characterize rejection performance, is defined for point and extended sources. The manner in which the scattering rejection ratio is evaluated for each major scattering source by means of a succession of manual and computer operations is outlined. The diffraction process is described, along with the method of evaluating diffraction rejection ratio. The method of obtaining the rejection ratio for an extended source by summing all of the point source rejection ratios is formulated for the case where the earth is the extended source.
