得益于单光子探测器的超高灵敏度, 光子计数成像系统近年来成为极弱光探测成像领域的研究热点. 基于单点扫描的光子计数成像系统, 以光子累积的方式获取大量返回光子事件后重建目标图像. 然而, 单像素探测时间固定导致的光子事件累积冗余或累积不足的问题, 限制了系统的成像效率. 本文提出了一种基于自动选取单像素最佳累积时间的时间自适应扫描方法, 并分别进行了单点测距和扫描成像实验. 结果表明, 本文提出的方法在重建质量接近的深度图像(64 × 88)时的数据总获取时间相比单像素固定累积时间的扫描方法降低了一个数量级, 极大地提高了扫描数据获取的效率, 为光子计数成像系统快速成像提供了新思路.Photon counting imaging system has recently received a lot of attention in ultra-weak light detection. It has high sensitivity and temporal resolution. The single-point scanning photon counting imaging system typically accumulates a large number of photon events to reconstruct depth image. Acquisition time is redundant or insufficient, which limits imaging efficiency. In this work, a new method called adaptive acquisition time scanning method (AATSM) is proposed to solve this dilemma. Comparing with the fixed acquisition time of every pixel, the method can automatically select the acquisition time of per pixel to reduce total time of data collecting while obtaining depth images. In experiment, we acquire the depth images with the same quality by different scanning methods, showing the feasibility of AATSM. The total time of collecting data by the AATSM can be reduced to 11.87%, compared with fixed acquisition time of every pixel. This demonstrates the capability of speed scanning of AATSM, which can be used for the fast imaging of photon counting system.
