Abstract
Disclosed is a system and a method for detecting the presence of one or more objects in a turbid medium, the method including: illuminating at least a portion of the turbid medium with incident light having at least one wavelength which interacts with the one or more objects contained in the turbid medium differently than the incident light interacts with the turbid medium; measuring light that emerges from the turbid medium; and detecting and locating the one or more objects using Independent Component Analysis (ICA) of the emergent light from the turbid medium. The present invention is useful for medical applications, such as for finding and locating, a tumor(s) in body organs, or excised tissues. Moreover, the present invention can be used to locate objects in obscuring medium, such as, mines in shallow coastal water, a plane in fog, military targets under fog, smoke or cloud cover.
