| Abstract: | Combining the modulation actions of turbulent atmosphere for laser speckle intensity and beam transmitting direction, and the averaging effects of the receiving aperture for the intensity and phase fluctuations, we discuss the problems cf the probability density functions, aperture average effects of intensityscintillations and phase fluctuations of laser speckle. The sperture averagefactor of the high order moments of intensity ls obtained. |
