Abstract
Two optical measurement techniques are presented for imaging of strain and temperature of high temperature materials used in turbine engines. The proposed strain measurement capability is provided by a variant of electronic speckle pattern interferometry (ESPI), whereas temperature imaging is achieved with thermographic phosphors. The proposed methods are suited for use on both coated and uncoated specimens, and will be designed around thermo-mechanical fatigue test facilities under development elsewhere. One particularly innovative aspect is the prospect of depth resolved lateral strain imaging within and through a ceramic coating. The Phase I work plan consists of a demonstration of the measurement capabilities, an analysis of critical components and feasible operating envelope, and a detailed Phase II design and development strategy.
