Microcontroller Information-Measuring Systems on Bragg Gratings

The urgency of the work devoted to the creation of modern microcontroller information-measuring systems based on Bragg gratings is formulated. The advantages of a sensitive element based on the Bragg grating (FBG) are determined, the prospects of its application for measuring various physical quantities. The structure, the main parameters of the sensitive element with the use of Bragg gratings are described. The possibilities of application for measuring various parameters on the basis of determining the dependence of the resonant wavelength on the measured parameters are shown. Based on the analysis of known patent and technical sources, structural diagrams of the developed sensors and information-measuring systems were studied. The general structure of FBG-based systems is determined. In this paper, we propose an information-measuring system for vibration parameters based on a sensitive element with an FBG, the principle of operation, the main characteristics are shown.
