1.目的本程序目的是在各种预期的工作条件下,评价激光测距仪的性能和安全特性。 2.背景在过去几年中激光器的发展,促使它们在各方面的应用。激光器由于它的单色性好,高亮度及功率密度和窄脉冲等特点使它成为有用的工具。按照波长、温度、转换效率、激励方法、功率输出和其它特征,可以分成 1. Purpose The purpose of this procedure is to evaluate the performance and safety features of laser range finders under a variety of anticipated working conditions. 2. Background The development of lasers in the past few years has prompted their use in various fields. The laser is a useful tool because of its good monochromaticity, high brightness, power density and narrow pulse. According to the wavelength, temperature, conversion efficiency, excitation methods, power output and other features, can be divided into
