Paper Abstract

We describe an experimental method, using Michelson Interferometry and fourier transform, to determine wave fronts deformations after double passage through a wavy air-water interface. We consider the statistical aspect by using the averaged fourier spectra over many independent realizations. The spreading of fourier spatial spectra obtained from interferometric images can be used to determine heterodyne efficiency in airborne hydrographic systems using optical coherent detection.
