Abstract

For improving underwater visibility for robots, a method is presented using a special intervallic series of light pulses, two acts of emitting and receiving are performed by two specially designed optical shutters, and the control signals are delay synchronized. Calculations show that the received backscattering light can be reduced and so the visible distance increased. This method has several advantages which can make it practical for underwater robots and other actual uses. Its feasibility has been demonstrated in the experiments, while only in principle due to the limitation of the experimental conditions at present.
