Abstract :
Summary form only given. We propose a novel method for optical interferometric imaging through multiply scattering media. This method uses a long coherence laser and eliminates the need to scan the object. In our proposed method, the in-phase and the out-of-phase waves emerging from a randomly scattering media are imaged on a vidicon camera along with a reference plane wave. Subtraction of the images (in-phase and out-of-phase) yields a reconstructed image with background optical noises removed.
