  • Optical method for detecting displacements and strains at ultra-high temperatures during thermo-mechanical testing
    Patent number: 9400237
    Abstract: An ultra-high temperature optical method incorporates speckle optics for sensing displacement and strain measurements well above conventional measurement techniques. High temperature pattern materials are used which can endure experimental high temperature environments while simultaneously having a minimum optical aberration. A purge medium is used to reduce or eliminate optical distortions and to reduce, and/or eliminate oxidation of the target specimen.
    Type: Grant
    Filed: March 17, 2014
    Date of Patent: July 26, 2016
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
