Laser active illuminated imaging : analysis and experimental demonstrations
The laser active illuminated imaging is one of the active imaging systems, which integrates laser technology 、range gate technology of imaging sensor 、imaging and manipulation technology of faint target. Near-infrared laser is utilized as illuminated source, the objects are detected and imaging in weak brightness and long ranges. The detected object is illuminated by laser and taken photos by CCD camera. The back-scattering of air is primary factor to affect the resolution of images acquired by laser active illuminated imaging system, so influence that the back-scattering of air to laser-illuminated imaging is analyzed, and the scattering phase function is discussed and calculated in this paper. The back-scattering physical model of laser active illuminating is set up, and the actual back-scattering affect function is put forward, also theoretic analysis is given. The laser active illuminated imaging system is designed to demonstrate the utility of laser-illuminated imaging for high-resolution clandestine nighttime surveillance from a simulated platform at long ranges, and tested the back-scattering model, the method of mitigate back-scattering effects is also put forward.
