Abstract

A two-point, joint-probability-density function for the intensity of a laser-generated speckle field after propagation through turbulence is developed by using the method of compound distributions. The parameters of the joint-density function are derived in terms of the path length, strength of turbulence, wave number, beam size, and degree of focus. Closed-form expressions for some of the joint moments of the intensity are developed and compared with experimental data. Good agreement is obtained.
