Imaging objects hidden in scattering media using a fluorescence–absorption technique

Abstract

A novel imaging technique is introduced to enhance the quality of an image of an object hidden in a highly scattering medium. In this technique, the object is made luminous, and its luminescent light is selected for imaging while the illuminating light is filtered out. The quality of the image can be further improved by selecting the portion of the luminescence spectrum that is strongly absorbed by the random medium.
