本文介绍了距离选通和同步扫描两种水下激光成像技术发展现状。从理论上计算了同步扫描系统的信号光和后向散射光传回到探测器端的辐照度与衰减长度的定量关系。减小视场角和增大光源到探测器的间隔可提高成像距离。一般水质下成像距离理论值约１２倍衰减长度。
This article describes the distance gated and synchronous scanning two kinds of underwater laser imaging technology status quo. The quantitative relationship between the irradiance and attenuation length of the signal and backscattered light transmitted back to the detector in the synchronous scanning system is theoretically calculated. Reduce the angle of view and increase the light source to the detector interval can improve imaging distance. Under normal water quality imaging about 12 times the theoretical length of attenuation length.
