用于激光雷达的高精度脉冲延时及脉宽控制研究
Research on High Precision Pulsed Delay and Pulse Width Control based on Laser Lidar
摘要
Abstract
Based on the fact that laser lidar range gated can selectively acquire echo signal at different distances,a circuit of pulse delay time and pulse width control is designed based on delay generator AD9501 and microcontroller.Host computer software is designed based on LabVIEW.The circuit finally achieves 16 bit data delay adjustment by double AD9501 in series and 8 bit data pulse width adjustment by the third AD9501 and RS flip flop.The experimental results indicate that the circuit can calibrate in 1. 8μs delay range with delay accuracy of about 30 ps and inherent delay of 280 ns after adjustment of the cir-cuit and host computer,fully meeting the requirements for laser lidar range gated.关键词
