Study on Self-Triggering Pulsed Time-of-Flight Laser Rangefinding

提出了一种新型脉冲激光测距方法———自触发脉冲飞行时间激光测距方法。该方法有效解决了传统脉冲激光测距法中存在的提高测距精度和缩短测量时间两者之间的矛盾。对该方法及本质特点进行了详细描述和理论分析 ,并给出用以描述该方法的基本方程。最后 ,给出了实验装置 ,在 2 0m范围内获得了 0 5mm的测距精度。

Based on the self-triggering pulsed technique, a novel pulsed time-of-flight laser rangefinding method is proposed to improve the accuracy and measuring speed of laser distance measurement. The theoretical analysis is carried out, and three basic equations are presented to describe the methods. Furthermore, a measurement device is described and experimental evidence is presented to show the feasibility of measuring distance with 0 5 mm resolution over 20 m ranges.
