Paper Abstract

The micro-optic Fabry-Perot interferometer as a spectral transducer for fiber optic sensors is described. Signal processing includes the simultaneous detection of several resonances of the FPI response function in the spectral domain and the recovery of interference order for the exploited resonance. The application of this approach in displacement pressure and temperature sensors is demonstrated. The absolute accuracy of displacement sensing less than 1 nm was obtained. The dynamic range of the devices based on the proposed principles can be as large as 50 dB.
