摘要
激光主动照明成像技术是以近红外激光作为照明光源 ,对低照度情况下 ,远距离目标进行探测成像。由激光照射到待探测的目标上 ,用CCD相机对目标进行拍摄 ,分析了大气后向散射对成像系统影响 ,并利用距离选通技术可大大增加目标探测能力和探测距离。实际大气条件下的激光照明成像实验 ,对理论进行了验证。
The laser active illuminated imaging technology utiliz es near-infrared laser as illuminated source, the objects are detected and imaging in weak brightness and long range. The detected object is illuminated by laser and taken photos by CCD camera, the effect that back-scattering of the atmospher e to the imaging system is analyzed, the detecting capability and range to objec t will improved by using technology of the range gated. Under actual atmosphere, the theory is tested by the experiment of the laser active illuminated imaging.
