利用国内的元器件建立了声光调制CO_2激光外差接收系统,并进行了实验室内静止目标的实时强度成像,成像距离3m,成像视场7°× 5°,像素128×98,4个颜色梯度显示像强度. A CO 2 laser heterodyne receiving system was established by using domestic components. The real-time intensity imaging of the stationary target in the laboratory was performed. The imaging distance was 3 m, the imaging field was 7 ° × 5 °, and the number of pixels was 128 × 98. Color gradient shows image intensity.
