采用固态结构的雪崩光电二极管，利用其工作在盖革模式下的单光子探测能力，构建了光子计数成像实验系统。通过实验验证，该系统在10-3lx环境照度下，借助VC++开发的数据采集平台，通过点扫描方式将离散为12×12的二维图像信号输出为144个采样点对应的144组光子计数频率。按照统计光学中光场随机涨落存在的统计规律，求取每组光子计数频率的期望并组成12×12的二维数字矩阵。根据每一采样点的光子计数频率值与图像的灰度值成正比的关系，实现了将光子计数频率矩阵恢复为二维图像的过程。该实验系统的全固态结构不但提高了系统的可靠性，而且减小了系统的体积。系统工作电压低于35 V，暗计数小于4 Hz。

On the basis of a solid-state Geiger mode avalanche photodiode (APD) to detect a single photon, a photon counting imaging experimental system was built. The system was placed in 10-3 lx illumination environment. A 2-dimension image was divided into 12×12 samples and examined by point scanning mode. 144 groups of photon counting frequencies were obtained corresponding to 144 samples by the data acquisition platform designed with VC++. The expectation of each group of photon counting frequencies was calculated based on the statistical law of light field fluctuations. A 2-dimension matrix was made up of 144 expectations. Because the gray level of image was proportional to the expectation of photon counting frequency, the 2-dimension image was restored according to the matrix. All-solid state structure not only increases robustness but also decreases the size of the experimental system. The operating voltage of the system is less than 35 V; the dark counts are below 4 Hz.
