IFOS announces award of Phase I SBIR for “Ultra-Fast Fiber-Optic Fish-Net System for Hit-Point Detection.”

To address highly integrated instrumentation that can be used to determine impact position and attributes, IFOS is developing a fiber-optic “fish net” with embedded Fiber Bragg Grating (FBG)sensors as a hit grid to determine the hit point. In Phase I, IFOS will demonstrate feasibility by constructing and testing a proof-of-principal model based on a high-speed/high-resolution FBG interrogator with advanced signal processing algorithms to identify the hit point in a test coupon. The proposed innovation is the miniaturized hit grid package including sensors and interrogator based on all-fiber-optic sensing system replacing the existing electrical sensors/cabling and reducing the system weight, cost, size, footprint while improving performance and reliability. The hit grid package also will contain an integrated, high-efficiency telemetry transmitter to address potential bandwidth and link margin issues due to high bit rates.
