Multichannel Hybrid Integrated Optic Fiber Bragg Grating Sensor Interrogator

Redondo Optics Inc. (ROI) proposes to develop a miniature fiber Bragg grating sensor interrogator, FBG-TransceiverT, system based on ROI's proprietary multi-channel integrated optic sensor (InOSenseT) microchip technology. ROI's InOSenseT technology allows the integration of all of the functionalities, passive and active, of conventional bench top FBG sensor interrogators such as the IFOS system, with no moving parts in a compact, low weight, low power, hermetic sealed small form factor (SFF) package, operating at signal rates up to 20 kHz. In Phase I, ROI will design and develop a proof-of-concept demonstration of the integrated, FBG-TransceiverT, FBG sensor interrogator, in Phase II, ROI will engineer and field deploy the FBG-TransceiverT system at a selected naval vessel for environmental qualification. The FBG-TransceiverT system can easily interface into any of the Navy's current and future tactical solid fuel rocket motors to provide real time environmental and structural health monitoring. ROI's miniature and low cost, FBG-TransceiverT system is poised to revolutionize the field of fiber optic structural health monitors and gain a rapid acceptance into the well established and fast growing structural health monitoring and nondestructive inspection (SHM/NDI) $480 million U.S. market.
