摘　　要：简单介绍了半导体脉冲扫描激光雷达距离成像和强度成像的基本原理,并分析了回波信号采集与处理系统需要达到的条件,进而设计出了一套以DSO2902虚拟示波器和计算机为核心的扫描激光雷达数据采集与处理系统。通过编写的VB程序对其进行控制,使其满足对激光雷达回波信号的采集要求,对回波信号进行采集。对基于VB6.0语言的成像方法进行分析,并研究了一套基于MSChart控件的成像系统。The basic principles of range imaging and strength imaging of the semiconductor pulse laser radar are introduced briefly in this paper. The conditions required to achieve by echo signal acquisition and processing system are analyzed. And then a scanning laser radar data acquisition and processing system with DSO2902 virtual oscilloscope and computer as the cores is put forward. Controlled by the VB program , the system can meet the requirements of collecting the laser radar echo signals. The imaging method of VB6.0 language is analyzed and an imaging system based on MSChart control is presented.
