| Abstract: | The structure of Low-light-level (LLL)image photon counting intensifier is introduced and the differences between norm’al generation Ⅰ intensifiers and the LLL image photon counting intensifier are given in this paper.Based on the single channel photon counting technique,the measurement principle and method of the LLL image photon counting intensifier’s major parameters-photon gain-are presented. The test equipment has been constructed and the photon gains of the LLL image photon counting intensifier have been measured in different conditions. The measured results are compared with the brightness gains of normal generation Ⅱ intensifiers. The approximate formula of the intensifier’s photon gain is given. |
