摘　　要：提出了微光图象光子计数器象管主要参数（暗计数、光子增益）的测试原理和方法，建立了测试系统．对微光图象光子计数器象管的暗计数和光子增益进行了实测，给出了测试结果。The structure of low light level (LLL) image photon counting intensifier is introduced, and the differences between normal generation Ⅱ intensifiers and the LLL image photon counting intensifier are given. Based on the single channel photon counting technique, the measurement principle and method of the LLL image photon counting intensifiers major parameters dark count and photon gain are presented. The test equipment has been constructed, and the test procedure is described. The experiment results and its comparison with normal generation Ⅱ intensifiers are provided.
