Multichannel Hybrid Integrated Optic Fiber Bragg Grating Sensor Interrogator Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-115 Topic Title: Multichannel Hybrid Integrated Optic Fiber Bragg Grating Sensor Interrogator Proposal No.: N052-115-0473 Firm: Redondo Optics, Inc. 811 N. Catalina Avenue, Suite 3120 Redondo Beach, California 90277-2198 Contact: edgar Mendoza Phone: (310) 292-7673 Abstract: 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. Benefits: ROI's FBG-TransceiverT system represents a new, highly robust and reliable, technology that can be use to accurately monitor the status of an array of distributed fiber optic Bragg grating sensors install in critical infrastructures. Its miniature package, low power operation, and state-of-the-art data communications architecture, all at a very affordable price, makes it a very attractive solution for a large number of SHM/NDI applications in aerospace, naval and maritime industry, civil structures like bridges, buildings and dams, the oil and chemical industry, and for homeland security applications.
