| Abstract: | 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. |
