Novel Fiber Optic Field Sensor

This proposal addresses the fabrication of a novel fiber optic field sensor, having significant performance and cost advantages over the competing technologies. Fiber optic based sensors offer attractive features of immunity to electromagneticinterference, excellent electrical isolation, compatible with modern networks, high reliability, and compactness, which enable such sensors to monitor and control remotely and securely. However, current fiber optic sensors are hampered in practicalapplication due to their low sensitivity and high cost. In this program, Agiltron Corporation proposes a new type of fiber optic field sensor, based on recent progress in ferroelectric crystal materials having extraordinary field-response properties. Thedesign is simple in construction and easy to operate. This technology holds a promise to fabricate fiberoptic sensors with drastically simplified manufacturing steps. In phase I, we propose to demonstrate a prototype integrated fiberoptic sensor whichhas both performance and cost advantage.Success in the Phase I effort will identify a viable manufacturing route for high-performance fiber optic sensor. These low cost devices have a wide range of
