Abstract

We use heterodyne detection to characterize the Wigner phase space distribution W(x,p) of an optical field in position x and momentum p. This method yields smoothed Wigner phase space distributions directly as contour plots and can be applied with either coherent or low coherence light sources. The measured phase space distributions are used to characterize the light sources and to study light propagation in multiple scattering media. These techniques may find important applications in understanding and enhancing images obtained in coherence tomography.
