Analysis and research on backscattering effect of underwater imaging
Yang Meng Lin Shi · 2022
In laser underwater imaging, backscattered light is the main component received by the detector. Backscattered light reduces the contrast of underwater image target and restricts the application of underwater image. The stripe laser scanning imaging method can meet the requirements of underwater laser imaging system to increase the field of view and reduce the influence of backscattered light. In this paper, combined with the transmission characteristics of laser in underwater, we establish the calculation model of backscattered light, This model is of guiding significance to analyze the influence of illumination system on imaging quality and the optimization of light source in underwater imaging system.
