Design and implementation of Range-gated Underwater Laser Imaging System

摘要

A range-gated underwater laser imaging system is designed and implemented in this article, which is made up of laser illumination subsystem, photoelectric imaging subsystem and control subsystem. The experiment of underwater target drone detection has been done, the target of distance 40m far from the range-gated underwater laser imaging system can be imaged in the pool which water attenuation coefficient is 0.159m~(-1). Experimental results show that the range-gated underwater laser imaging system can detect underwater objects effectively.
