脉冲调制无扫描激光三维雷达模拟方案的研究

提出了一种脉冲调制无扫描激光三维雷达模拟系统的方案。激光脉冲的实际飞行时间可以通过控制激光管发出激光脉冲的时间来模拟。并同时对APD管施加高压调制,处理积分测量得到的数据,计算出模拟的激光传输距离。还讨论了系统控制模块的设计。该方案具有成本较低,结构简单等优点,可用于验证脉冲调制原理方案,并作为该项研究的前期准备。

The research of the APD simulative system of scannerless 3D lidar based on pulse amplification modulation

This paper presents a way of scannerless 3D lidar simulative system based on pulse amplification modulation.The actual time of the flight of laser pulse can be simulated by controlling the time when LD emits laser pulse.The high-voltage modulation is put on APD synchronously and the data acquired by integral measurement can be dealt with to figure out the simulative laser transmitting distance.The design of the system-control module is also discussed in the paper.This project has the advantages such as low cost,simple structure and so on,and can be used to prove the principle of pulse amplification modulation as the former preparation of the research.
