Аннотация
A method for detecting changes in the length of an optical cavity is proposed for fiber-optic sensors based on the Fabry–Perot interferometer scheme. The possibility of detecting oscillations of the resonator length at the subnanometer level in the frequency band 1.5–300 kHz is shown. The sensitivity was 0.3 nm in standard deviation. The proposed scheme makes it possible to reliably distinguish high-frequency oscillations against the background of slow drifts of the sensor length caused by temperature fluctuations or deformations.
