We describe a scanning time-of-flight system which uses the time-correlated single-photon counting technique to produce three-dimensional depth images of distant, noncooperative surfaces when these targets are illuminated by a kHz to MHz repetition rate pulsed laser source. The data for the scene are acquired using a scanning optical system and an individual single-photon detector. Depth images have been successfully acquired with centimeter xyz resolution, in daylight conditions, for low-signature targets in field trials at distances of up to 325 m using an output illumination with an average optical power of less than 50 microW.
我们描述了一种扫描飞行时间系统，当远处的非合作目标由千赫兹至兆赫兹重复率的脉冲激光源照射时，该系统使用时间相关单光子计数技术来生成这些目标的三维深度图像。场景数据通过扫描光学系统和单个单光子探测器采集。在日光条件下，使用平均光功率小于50微瓦的输出照明，在距离高达325米的野外试验中，已成功获取了厘米级xyz分辨率的低特征目标深度图像。
