Abstract
A polarization-based colposcopy apparatus includes a polarization exchanging beam splitter pair oriented so that s- and p-polarizations are exchanged. An optical flux from a specimen is directed through the pair, and orthogonal components thereof are alternately or selectively coupled to an array detector. The detected images are processed based on image correlations to reveal specimen structures.
