An image of a planar object obscured by a moving diffuser can be obtai
ned if the diffuser is illuminated by a spatially coherent quasi-monoc
hromatic plane wave and coherence measurements are made on the wave fi
eld reflected by the object back through the diffuser. The image distr
ibution is given by the intensity that would be observed were the obje
ct illuminated directly by a plane wave and the reflected wave allowed
to propagate one half of the diffuser-object distance.
