Imaging diffuser-obscured objects by making coherence measurements on enhanced backscatter radiation

Abstract

An image of a planar object obscured by a moving diffuser can be obtained if the diffuser is illuminated by a spatially coherent quasi-monochromatic plane wave and coherence measurements are made on the wave field reflected by the object back through the diffuser. The image distribution is given by the intensity that would be observed were the object illuminated directly by a plane wave and the reflected wave allowed to propagate one half of the diffuser–object distance.
