摘　　要：高速多道光子计数单元是激光雷达系统的关键部件之一,关系到激光雷达数据采集的正确性与系统的性价比。依据一个新的设计思路,我们采用TI公司的DSP(Digital Signal Processing)芯片搭建了一个试验平台,实现高速多道计数的功能。利用该平台在激光雷达上进行了回波信号的采集测试。实测结果表明,DSPs(Digital Signal Processers)能很好的执行高速多道计数,可开发出高性价比的高速多道计数卡。Multi-channel photon counting unit is one of primary components of a lidar,which relates to the performance of the lidarsystem. In this paper,a new multi channel photon counting unit with TI＇s DSPs as the core to be used in the design is described,and a test was carried out in the lidar. The results confirmed that a high quality and low price scalars using the DSPs is feasible.
