一、前言用激光测距最大的价值是使测定范围大大的扩展了。用光测距目前有:1.光波干涉法;2.调制光波法;3.激光雷达等三种。二次世界大战后,光波干涉测定用的光源有了很大的进步。同位素灯管的使用范围不过800毫
First, the foreword The biggest value of the laser ranging is to greatly expand the scope of the determination. Light ranging are: 1. Lightwave interferometry; 2. Modulation light wave method; 3. Lidar and other three. After World War II, the light source used for the determination of light interference has been greatly improved. The use of isotope lamps but 800 milliliters
