  • Method to characterize cut gemstones using optical coherence tomography
    Patent number: 10458921
    Abstract: The invention includes an improvement in a method of assessing a gemstone having at least one planar face with an internally reflecting surface including the steps of optically modifying the at least one planar face of the gemstone to return a sample beam from an internally reflecting plane corresponding to the at least one planar face to an optical coherence tomography (OCT) system; selectively directing the sample beam from an optical coherence tomography (OCT) system onto the gemstone; and generating an OCT image map of the gemstone to determine volume, gem carat weight and/or quality.
    Type: Grant

    Date of Patent: October 29, 2019
    Assignee: The Regents of the University of California
    Inventors: Matthew Brenner, Andrew Emon Heidari, Zhongping Chen, Sari Mahon, Joseph Jing
