摘　　要：给出1.57μm人眼安全激光测距仪的光学设计方法,根据薄透镜系统的初级像差理论,使用PW法确定测距仪光学系统的初始结构,进而利用Zemax软件设计出一种对称式测距光学系统并对其进行优化。该光学系统结构简单,加工组装方便,成本低,且能满足测距仪对其光学系统的发射部分和接收部分的性能要求。We introduce a design method of the 1.57 μm eye-safe laser range-finder′s optical system. It utilizes the PW method according to the primary aberration theory of thin lens system to determine the initial structure of the range-finder′s optical system. A symmetric structure of range-finder′s optical system is designed by the Zemax software. After optimization, the symmetric optical system not only has the simple structure, convenient processing and assembly and low cost, but also satisfies the requirements of the performance of the range-finder′s emitting and receiving parts.
