A research and development program will be done to develop a differential common path interferometric temperature sensor. An Analytical study will be done in order to obtain a parametric study Of the interferometric system and to permit a selection of a design Suitable for a technology demonstration of a temperature sensor Suitable for noncontact measurements in a hostile environment. The Approach selected will be developed and experimentally evaluated to Show its potential for in-situ temperature measurements of rapidly Changing or rapidly moving hot surfaces such as laser irradiated Targets, laser nozzles, or turbine blades.
