| Under photoelectric imaging is an effect complement of sonar detection. Due to thebackward scattering of under-water initiative imaging, detecting distance is limited. Andconventional gate-ranged imaging only get the image of certain distance, thus the detectingrange is restricted, it is disadvantage for target detecting and identifying. In this articleseveral mechanisms were applied, such as the best spectrum technology research forunder-water illumination, the matching research between photosource spectrum and imageintensifiers, under-water low-light-level image system research. Gate-ranged system forunder-water low-light-level imaging and two kinds of control circuits for system test weredesigned, so was the equipment; Ground experiments for low-light-level/laser gate-rangedimaging were done and the experiments provided perfect results. |
