Abstract

The general configuration of a satellite telescope is used to show how simple projections of the various limiting apertures onto a chosen plane can show the obscuration and vignetting at any selected position on the focal plane. The projections also indicate what por-tions of the walls, baffles, etc. are viewed from various positions on the focal plane. Again projections taken at the angle of external sources show what portions of the interior are illuminated by these sources and the two combined give a method of estimating stray rad-iation. Since most detectors in scanning systems are AC coupled, the ability to estimate the rate of change of stray light with time is demonstrated.
