Paper Abstract

For improving definition of underwater image, a method using special intervallic series of light pulse, and two acts of emitting and receiving are synchronized exactly is presented. The structure of the device which include a special designed emergent-incident optical shutter is also described. Brief calculation show that the back-scattering light can be reduced, and so the definition of underwater image increased effectively. This method has several advantages, which can make it practical for wide use.
