摘　　要：采用扫描发射、收发合置、外差探测等技术建立了一台CO2 激光扫描成像演示系统。利用雷达距离方程计算了系统的最大作用距离 ,并对室内 5m处的目标及室外 5 78m远处的大楼做了成像实验 ,扫描角度为± 2°×±1° ,获得了每秒 10帧、每帧 32行的轮廓像。This paper reported a CO2 laser scanning imaging demo system adopting the technology of scanning transmit, the same antenna for receiving and transmitting, heterodyne detection etc. The maximum operation distance of the system was calculated by using the radar distance equation. The imaging experiment with the targets 5 meters away indoors and the building 578 meters away outdoors, with the viewpoint of ±2° × ±1° is carried out. The outline picture of 10 frames per second, and 32 rows per frame are obtained.
