TELESCOPE DESIGN FOR GROUND SURVEILLANCE FROM HIGH ALTITUDE SATELLITES,

Abstract

Some of the problems pertinent to the basic design of telescopes for use in high altitude satellites are discussed. Some type of sensing device, such as a camera tube, is assumed to be an integral part of the system. The philosophy that the resolution of the sensor should be matched to the obtainable diffraction limit of the telescope was followed, although in practice, lenses or mirrors much larger than 2-2/1/2 feet in diameter are limited by grinding imperfections rather than by diffraction effects.
