本文介绍使用米级精度的激光测距机中的激光发射装置,而原接收装置中的回波接收放大器改用恒比定时电路,原米级分辨率的测距计数器改用厘米级分辨率的测距计数器,在1979年第四季度和1980年第二季度进行了测距精度试验,报导了试验结果。试验结果表明,应用恒比定时电路和高分辨率计数器以后,脉冲激光测距机的精度有显著提高,均方误差从原来的60厘米左右减小到20厘米以下。
This article describes the use of laser-range accuracy of the laser range finder laser transmitter, and the original receiving device to receive the constant-frequency receiver instead of timing circuit, the original meter-level resolution of the distance meter instead of centimeter-class resolution Ranging counter, ranging precision test in the fourth quarter of 1979 and the second quarter of 1980, reported the test results. The experimental results show that the accuracy of the pulsed laser range finder is significantly improved after the constant ratio timer circuit and the high resolution counter are applied, and the mean square error is reduced from about 60 centimeters to less than 20 centimeters.
