文摘In this paper an absorbing object hidden in a highly scattering medium is shown to be visibleunder the illumination of a cw coherent light by using interferometry,and a new filtering algorithm thethreshold density filter is used to extract interference pattern from the speckle noise background fast andefficiently. The submillimeter spatial resolution is achieved.
