Photon-correlation experiments have verified the theoretical prediction of Baltes et al. that a phase grating hidden by a diffuser can be detected by correlation measurements. We have additionally demonstrated that a simpler method of detecting the presence of the grating, valid for arbitrarily fine diffusers, is to measure the temporal autocorrelation of the intensity of the scattered field at a single point.
