Abstract

The phase-space description of signals is a joint space-spatial frequency representation in local domain. It employ the phase-space representation functions to describe the property of optical signals between two variables that form a Fourier transform pair and provide a valuable analysis tool for signals when this new mathematical analysis tool applied to an optical system. This method can also be applied to the analysis of propagation of laser beam within free space or atmosphere condition. In this paper, we give the analytical formula of optical field distribution of laser beam after propagation within turbulence in the domain of phase-space. The results show an instructing aspect of optical signal propagation and are helpful to the future application of phase-space method to the laser communications.
