Abstract

An optical fiber strain-rate sensor based on in-line Doppler velocimetry is developed using a 3 × 3 coupler with a large path imbalance Mach-Zehnder interferometer for passive demodulation of Doppler wavelength shifts. A model is developed that relates the strain-rate in an optical fiber to the corresponding Doppler wavelength shifts. The strain-rate obtained by differentiating strain from a Michelson strain sensor mounted on the PZT cylinder shows good agreement with the strain-rate directly obtained from the Doppler-based strain-rate sensor.
