摘　　要：为了实现极微弱光环境下的目标探测成像,采用在盖革模式下工作的固态雪崩光电二极管作为探测单元,搭建了光子计数成像实验装置;然后通过装置得到的灰度等级测试图的光子计数频率值,建立了反映光子计数频率与图像灰度之间关系的光子计数成像灰度模型。基于此模型得到了较好的目标光子计数图像。In order to achieve the target detection and imaging in ultra weak light environment,the solid state avalanche photodiode in Geiger mode is used as the detection unit to build the photon counting imaging experimental setup at the illumination of 10-3 lx.The photon counting frequencies of the gray level images can be obtained.The photon counting imaging gray level model that shows the relationship between photon counting frequency and gray level is developed based on the experimental results and the statistical model of photon counting at low light illumination environment.The photon counting images are obtained by simulations based on the model.
