摘要
介绍了把脉冲自触发技术与双光路误差模型应用于激光测距系统,从而完成精密距离测量的一种测量技术。探讨了将脉冲自触发技术、恒比值时点判别技术以及光路系统误差修正技术相结合而实现的高精度时间测量的测量原理与实现,并根据实验结果进行了定性分析。
This paper introduced a new laser range testing method which has high precision based on the Selftriggering Pulsed technology and the error model. The technologies of Self-triggering Pulsed, Constant Fraction Discriminator and the system error model, which were used for the high precision laser range finding, were presented in this paper. In the end, experiment result was presented, which was consistent with theories used in the laser range testing system.
