摘要：

基于AD500-9型雪崩光电二极管设计以窄脉冲发射、雪崩光电二极管偏置、弱光信号处理和计时电路为主要结构的激光测距系统. 利用标准时基发生器对计时电路进行验证, 采用线性拟合方法使时间测量的精度为10^-10量级. 采用软件校准方法将测距实验中的测量误差控制在±0.1 m以内, 并对误差进行分析.

Abstract:

Laser ranging system was designed based on AD500-9. The system is composed of four parts: narrow pulse laser emission circuit, APD bias circuit, weak photoelectricity signal processing circuit, and time measurement circuit. The timing circuit was tested and verified with selfdesigned standard timing generator. It has realized 10^-10 level time measurement via linear fitting. The analysis shows the distance measurement error is limited to ±0.1 m in outdoor ranging experiment by software calibration method.

Key words: avalanche photo diode(APD), bias circuit, laser ranging, weak photoelectricity signal processing
