摘要

本文发展了一种基于高精度单光子探测器的激光测距方法, 实现了百微米量级精度的非合作目标激光测距. 单光子测距系统引入参考位置, 有效地抑制了系统延时漂移, 使光子飞行时间测量精度达到0.5 ps, 在2 m测距距离处, 单光子测距系统的测距精度达到65 µm@RMS. 这项工作达到了当前脉冲飞行时间测距最高精度水平, 为远距离非合作目标高精度测距和成像提供了一种有效的技术.

Single-photon detectors based on avalanche photodiodes and time-correlated single-photon counting technology are widely used in pulsed laser ranging. The ranging accuracy is one of the most important performances of laser ranging. In this work, a laser ranging method based on high-precision single-photon detector is developed to achieve laser ranging for non-cooperative targets with hundred-micron-level ranging accuracy. In the system, a low-time jitter Si APD single photon detector, picosecond pulsed laser and high-precision timing counter are used to reduce the time jitter of the ranging system, and a reference position is added to suppress the influence of delay drift of the system. And a laser interferometer system with a ranging resolution of 1 nm and an accuracy of 0.5 ppm is used to calibrate the distance of each movement of the ranging target. The photon flight time accuracy of 0.5 ps is achieved while the integral time ≥ 3 s. The ranging accuracy of 65 μm@RMS is realized, while the target is 2 m away. This work is one of the highest levels of pulsed time-of-flight ranging, and provides an effective technology for high-precision ranging and imaging of long-range non-cooperative targets.
