Thermal History Optical Readout (THOR) System for Condition Based Maintenance

Physical Sciences Inc. proposes a novel and highly robust Thermal History Optical Reader (THOR) system concept capitalizing on mature optical, processing, and software technology developed by PSI and proven in the condition based maintenance field for both DoD and commercial applications. The proposed portable battery operated system will allow the enabling technology for wirelessly recording a fingerprint of the thermal history of an array of glass-ceramic substrates developed by the Air Force to effectively and rapidly enter field evaluations and provide benefits for life prediction and health monitoring of components in extreme environments. Proven optical instrumentation and pattern recognition tools developed at PSI are presented that allow rapid development and demonstration of the THOR concept within the Phase I program.
