| Abstract: | Optical diversity is determined by the intensity correlation function, so in this paper, a method used to calculate spatial correlation of the optical power receiued by antennas when aperture averaging effect exists is presented and the change of the ratio of the signal to noise, the optical power probability distribution and the power spec tra resulting from diversity are discussed. The conclusion shows that spatical diuersity can improve greatly the performance of laser communication in atmosphere. |
