ABSTRACT:
A technique for forming an image of an object in or behind a scattering medium. In one embodiment, the object is made luminescent, and the luminescent light is selected for imaging while the illuminating light is filtered out. The quality of the image can be further improved by selected the portion of the luminescence spectrum that is strongly absorbed by the scattering medium.
