Optical Method for Detecting Displacements and Strains at Ultra-High Temperatures During Thermo-Mechanical Testing

NASA's Langley Research Center has developed an optical method for detecting displacements and strains at ultra-high temperatures during thermo-mechanical testing. This innovation will provide displacement and strain measurements in high-temperature applications where conventional measurement technologies cannot physically survive. The measurement system has operated in laboratory environments in excess of 2,800 °F.
