Abstract

The presented work compares the methods of probing classical fiber Bragg gratings and targeted fiber Bragg structures in problems of monitoring the parameters of mechanical vibrations. In the course of the work, a prototype of an acoustic system for continuous monitoring of processes based on Bragg gratings was developed and experimentally studied within the framework of trial operation; the limitations of measurement methods based on FBGs were shown. In the course of a comparative analysis of the response of the sensor to a homogeneous FBG and an equivalent AFBS circuit, it was revealed that the transition to addressable structures makes it possible to reduce the lower detected frequency by 3.3 times due to operation in the region of lower noise of the photodetector.
