  • Polarimetric accessory for colposcope
    Patent number: 9801536
    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.
    Type: Grant
    Filed: April 4, 2013
    Date of Patent: October 31, 2017
    Assignee: The United States of America, as represented by the Secretary, Department of Health and Human Services
