Interrogation system of signals from rotation sensors using tilted fiber Bragg gratings

Abstract

The paper herein is concerned with the system of interrogating the signals, entering from rotation sensors. The systems for analyzing the sensors thereof most often require capacity’s reference measurement. It allows obtaining the measurement’s higher resolution comparing to single-channel systems, in which it is impossible to measure the reference power. In case of single-channel solutions, there is most frequently tracked the wavelength shift, corresponding to the extreme, according to spectral specifications.

PUBLIC INTEREST STATEMENT

Relevance of the article to the general public

The developed measuring system of integration based on Bragg fiber gratings will have wide application. Fiber optic sensors can be used in:

- Automotive industry: refractometers for the operation of liquids; refractometers for monitoring the boiling point of the brake fluid;

- Food, agricultural and livestock industry: refractometers for honey—checking the amount of water that determines the quality of honey; refractometers for measuring the amount of sugar in solutions, fruit vegetable, milk drinks, syrups and juices. Refractometers for distillation of vodka and alcoholic beverages, in which the percentage of alcohol is measured; refractometers for measuring salt solution—determination of the amount of salt; refractometers for measuring oil and oil emulsion.

- Industrial technology: thermal machines, technical devices in facilities; refractometers for solar collectors, liquid cooling; metallurgical industry; oil and gas industry.

- Medical and veterinary service: refractometers for controlling the concentration of ascorbic acid and cetogulonic acid in the production of vitamin C; refractometers for blood analysis.
