| Abstract: | 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. |
