Paper Abstract

The design and performance characteristics of a series of structural-grade fiber Bragg grating based flexural beam accelerometers is reported. A concentrated mass added to the transducer allows for tailoring of the sensor's performance for specific applications. The sensors reported have sensitivities in the range 2-12.5 με/g, high resonant frequencies (>300 Hz), very low cross-axis sensitivity (∼40 dB below the main axis response), and low noise (∼1 mg/√Hz near 1 Hz). An array of these accelerometers was used in monitoring ship sub-structure motion, and selected results are presented.
