Abstract

For improved underwater visibility a method that uses a special intervallic series of light pulses and two acts of emitting and receiving is performed by two specially designed optical shutters and by control signals that are synchronously delayed. Calculations show that the apparent contrast of the target can be improved, and thus the distance over which it is visible can be increased. This method has several advantages that can make it practical for actual use, and its feasibility is demonstrated in experiments.
