Spectral Matching Factors for Photocathodes, Phosphor Screens, and Photographic Emulsions in Image Intensifier-Recorders Using Night-Sky Illumination, and Related Problems

摘要

The purpose of this paper is to assess the performance of basic components of opto-electronic image recording systems using night-sky illumination. The analysis is concerned with the matching efficiency between night-sky illumination and photocathodes, between photocathodes and phosphor screens and between phosphor screens and photographic films. To preserve resolution, a cascaded opto-electronic system must employ stages with maximum gain so that a minimum number of stages is contained in the system since especially each phosphor screen contributes to the deterioration of resolution.
