Paper Abstract

Sensitivity, resolution (MTF) and signal to noise ratio are three fundamental performances of a image intensifier, by which night system' detection range or image definition are mainly determined. On basis of photo-electronic imaging theory, a series of analysis and assessment are carried out in the paper on the limit value of the three performances. Under ideal specification conditions theoretical calculation results are given using several expressions, which is ≤ 6569μA/lm of limit sensitivity, ≤ 96 lp/mm of limit resolution and ≤ 64 of limit signal to noise ratio, respectively. These analysis method and results are useful as a strive goal and technical references for those skilled in the art.
