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。 A CO2 laser scanning imaging demonstration system was established by using techniques of scanning emission, transmitting and receiving, heterodyne detection and so on. The maximum range of the system was calculated by using the radar distance equation. The imaging experiment was performed at a distance of 5m at the indoor area and at an outdoor area of ​​5,78m. The scanning angle was ± 2 ° × ± 1 °, obtaining 10 frames per second. Contour image of 32 lines per frame.
