High temperature optical strain measurement system
Abstract
A high temperature strain measurement system being developed at the NASA Lewis Research Center utilizes laser speckle shift relations to measure strain components on the surface of a hot specimen in near real time. Features of this system include a totally noncontacting measurement capability and a rotatable gauge axis, allowing an optical rosette to be implemented and principal strains to be determined. Preliminary results and background work are presented.
