摘要:

通过对时间数字转换法进行时间间隔测量分析,设计出一款基于通用型TDC测量模块TDC-GP2的高精度时差测量系统。该系统测量范围为0~18 μs,精度可达到70 ps,有效地解决了激光测距、激光雷达等应用中高精度时差测量的问题。

关键词: TDC-GP2, 高精度时差测量系统, 激光测距, 系统设计

Abstract:

According to the analysis of time difference measurement by the method of TimetoDigital Converter (TDC),a highprecision time difference measurement system based on the general TDC module TDCGP2 is designed.The measurement range of the system is 0~18 μs and the precision can reach 70 ps.The system has effectively solved the problem of highprecision time difference measurement in application of laser ranging and LIDAR.

Key words: TDCGP2;highprecision time difference measurement system;laser ranging;system design
