Research abstract
OPTRA WILL DEVELOP AN ULTRA-HIGH TEMPERATURE LASER EXTENSOMETER FOR USE WITH LOAD FRAME TEST SAMPLES AS WELL AS STRUCTURES IN WIND TUNNELS. OPTRA PLANS TO MEASURE STRAINS AT 4000 F, ALTHOUGH THE EXTENSOMETER WILL HAVE A CAPABILITY UP TO 5500 F-WELL BEYOND THE CAPABILITY OF ANY EXISTING STRAIN MEASURING TECHNIQUES. THE EXTENSOMETER WILL PROVIDE 5 MICROSTRAIN RESOLUTION AND WILL HAVE AN ELECTRICAL BANDWIDTH SUFFICIENT FOR HIGH FREQUENCY CYCLIC TESTING (UP TO 500 HZ). IN ADDITION, THE ULTRA-HIGH TEMPERATURE LASER EXTENSOMETER WILL BE ENTIRELY NON-CONTACTING, REQUIRING ABSOLUTELY NO SAMPLE PREPARATION OF ANY KIND. THE EXTENSOMETER WILL BE ABLE TO HANDLE MOST MATERIALS, INCLUDING DARK COMPOSITES WITH LOW EMISSIVITIES. IN ADDITION TO DEMONSTRATING ULTRA-HIGH TEMPERATURE CAPABILITY, OPTRA WILL DEMONSTRATE THAT THE LASER EXTENSOMETER IS INSENSITIVE TO TURBULENCE CAUSED BY WIND TUNNEL FLOW.
