Abstract

This paper describes the development of a passively demodulated optical fiber sensor system capable of accommodating the high strain-rate events commonly encountered in applications involving stress wave propagation. This sensor system, which is based on in-line fiber etalon (ILFE) sensors and path-matched differential interferometry (PMDI), was tested experimentally at low frequency and strain-rates (time derivative of strain) up to (∼107 με/s). For the present system, this strain-rate corresponds to a sensor phase bandwidth of approximately 100 kHz. Characterization tests using sensor gauge lengths ranging from 260 to 350 μm showed that the sensor system had a minimum detectable phase of ∼2 microrad/√Hz rms at 2 kHz which corresponds to ∼0.8 nε/√Hz rms for 260 μm-gauge length sensor.
