Multi-Alloy Fabrication Method for Turboshaft Engines

Physical Optics Corporation (POC) proposes to investigate unique integrated optic gas sensors (IOGS) for real-time monitoring of hazardous chemicals in a fire/thermal/smoke environment. POC's proposed IOGS will: (1) use the most compact optic waveguidearray, both passive and active types, as the core portion of sensor to provide true pocket-size, lightweight, and comprehensive multiple sensor units; (2) use the state of the art wafer fusion technology as the key approach of sensor fabrication to providethe principal integrated sensor system, including light sources, guided-wave sensor array, and photodetecor array to realize the optical system-on-a-chip; and (3) use POC's proprietary intelligent neural network (INN) algorithm as the software base ofsensor signal-processing to provide real-time, multiple chemical element monitoring, discrimination, and classification with high sensitivity and accuracy. In the Phase II investigation, POC will: (1) improve the waveguide sensor array structure; (2)adapt an optimized wafer fusion process to improve sensor system integration; (3) improve and expand our INN algorithm for the required chemical-compound-sensing applications; (4) demonstate the sensor system's capability of real-time sensing of substancesof military interest, and, finally, (5) conduct, present, and document all scientific test results on the developed personal monitoring sampling sensors.
