The Elimination of Noise by the Optic Duplex Modulation

Abstract

The optic duplex modulation performed by using two kerr cells at the optic transmitter. The signals are recoverable at the receiver by using photodetector to respond the appropriate polarization components of light. The application of duplex modulation is to eliminate the noises due to atmospheric turbulence. The results of experiments shows that the atmospheric turbulent noises are really eliminated by the method. Finally the advantages and disadvantages to use kerr effect rather than pocket effect for optic modulation system are compared.
