THE LIMITING DETECTIVITY OF OPTICAL AMPLIFYING EQUIPMENT

Abstract

The limits in the ability to produce photographic recordings or visual detection of very faint celestial bodies in the presence of the sky background by using conventional photography and by employing optical amplification with contrast enhancement and high capacity storage target plates are investigated and compared. Equation are given which show the effects of the different variables involved for 3 types of imaging systems: (1) the conventional photographic system, (2) the image converter, and (3) the closed circuit television type of optical amplifier. The 3rd system was found superior to the 2 other systems.
