In this paper a 2D homodyne and heterodyne technique for imaging objects embedded in an opaque scattering medium is introduced. Our imaging approach is based on heterodyning of light with different Doppler shifts scattered from objects of two different textures or from an opaque object and a textured scattering medium. We report on the initial demonstration of pulling signals out of noise for an object hidden behind a scattering medium. Enhancements of signal- to-noise ratio of the order of 50 have been achieved utilizing a 2D holographic phase-sensitive detector.
