Abstract

Range gated imaging has high resolution and long detection range, but it can only image a certain range at a time, so the target search efficiency is low. The detection efficiency of full-range gated imaging can be improved effectively by allocating high repetition frequency laser pulses in different distance slices. In this paper, a coding assignment method for full-range gated imaging is designed, and an underwater laser imaging system is built for experimental testing. Experimental results show that this method can effectively realize underwater laser full gated imaging. The detection performance of full-range gated imaging is inferior to range gated imaging, but it is still far better than underwater continuous light imaging, which can effectively improve the search efficiency of underwater laser imaging.
