摘要
半导体激光器作为高精度激光自准直经纬仪的光源 ,所需解决的关键性问题是它的安全使用及在工作温度范围内其输出功率保持不变的问题 .本文提出了一种功率稳恒技术的新方法和它的驱动电源的设计 ,并在激光自准直经纬仪中应用 ,证明该设计方法结构简单 。
As the lamp house of high precision laser and auto collimation theodolite,the semiconductor laser is needed to solve the key problems:the safe application and the outputting power holding steadiness.This article brings forward a new method of power steadiness technology and the desiging of driving power supply.The method is used in laser auto collimation theodolite and be proved that the configuration is simple and the system is credible.
