Imaging through random scattering media by using cw broadband interferometry

Abstract

Imaging of an object hidden in random scattering media is achieved with cw broadband (white-light) interferometry. The light source is an inexpensive, easy-to-operate, superluminescent diode laser. An efficient image-enhancing algorithm is developed to eliminate the effect of phase noise in the interferometer and enhance the recovered image. Submillimeter spatial resolution is achieved.
