脉冲激光测距中高精度时间间隔系统设计
Design of high-precision time interval measuring system for pulsed laser range finding
摘要
Abstract
In the time interval measurement system,the time digital converter chip TDC⁃GP22 is adopted to realize the high⁃precision pulsed laser range finding,the high⁃performance microcomputer STM32 is taken as the main controller,and the semi⁃conductor laser diode SPLLL90⁃3 and AD500⁃9 are served as the receiving photoelectric detectors. The measured results are transmitted to the microcontroller through SPI communication interface,and then the processed data is transmitted to the display LCD12864. The test results indicate that the precision of the measuring method can reach up to 65 ps,and the system has sim⁃ple structure and high feasibility.关键词
