Paper Abstract

We demonstrate for the first time that the wave-function of a laser beam that has been distorted by a turbulent atmosphere can be measured instantaneously with a phase-shifting interferometer. Direct detection of the wave-function enables deriving the correlation function of various orders, including the mutual coherence function and other parameters that cannot be measured directly by existing methods. Experimental results are presented employing the proposed method to characterize a beam that was transmitted through a random phase-screen that imposed a Kolmogorov phase perturbation spectrum onto the beam.
