摘　　要：美国自适应光学联合公司(AOA)在哈佛大学 PAPA 探测器的基础上研制成功的光子数字化编址摄象机是一种具有极高探测灵敏度的光子计数式二维微光摄象机。采用多通道光学编码方法,可对光电倍增管探测到的每一个光电于事件产生相应的(x,y,T)时-空坐标数据,微机采集来自光子摄象机的数据流供实时图象显示和处理。The photon digitalizing camera,has been developed by Adaptive Optics Associates Inc.(AOA)based on the PAPA detector of Harvard Unlversity,and is a photon counting two dimensional low-light level camera with very high detec- ting sensitivity.By use of the multichannel optical coding method,it can provide corresponding time-space coordinate(x,y,T)data for every photoelectron event detected by photomultiplier anda microcomputer is used to collect data flow from the photon camera for the display and treatment of real-time image.
