  We introduce a practical digital holographic method capable of imaging
through a diffusive or scattering medium. The method relies on statistical
averaging from a rotating ground glass diffuser to negate the adverse effects
caused by speckle introduced by a first, static diffuser or scattering medium.
In particular, a setup based on Fourier transform holography is used to show
that an image can be recovered after scattering by introducing an additional
diffuser in the optical setup. This method is capable of recovering object
information from behind a scattering layer in biomedical or military imaging
applications.
