Abstract

Fiber-optic sensors based on fiber lasers and the light-excited microoptomechanical resonance structures are proposed and experimentally studied. The variants of multichannel measuring systems with frequency division multiplexing are considered. The number of the measurement channels and the needed power of the fiber laser are estimated. It is demonstrated that the frequency deviation of the microcavity can be measured in the limits \( \left| {\frac{{\Delta f}} {f}} \right| \) ≤ 0.1 with a relative error of ±2 × 10−6, which allows the creation of fiber-optic sensors with a measurement dynamic range of up to 2 × 104.
