Abstract

Photon-correlation experiments have verified the theoretical prediction of Baltes et al. [ Opt. Acta 28, 11– 28 ( 1981)] that a phase grating hidden within a diffuse medium may be detected by correlation measurements. By extension of this theory to the space–time domain we have additionally verified that a simple and more reliable method of detecting the grating, valid for arbitrarily fine diffusers, is possible by temporal autocorrelation measurements of the scattered field at a single point. This method is shown to yield detailed information about the deterministic and stochastic features of the source and the source plane motion.
