英文摘要	the technique of differential phase shift keying(dpsk) modulation is applied into demodulating phase information in the coherent optical receiver. the dual rate free-space receiving structure on the base of mach-zehnder delay interferometer with the lens is used suitably for differential delay which is equal to the one bit corresponding to a certain data rate. delay distance at the interference receiver is varied with transmission rata from satellite to ground. differential information is obtained by the subtraction of the two successive wave-front phases when made to interfere. the phase demodulation is extremely sensitive to phase fluctuation. because of the incident light through atmospheric turbulence, the wave-front of optical signal became jittered in the temporal and spatial domain rapidly. in the paper, the dual rate free-space laser communication receiver for phase lock to stable signal light phase is proposed, increasing the homodyne efficiency and decreasing the bit error rate.
