Abstract
An electro-mechanical mathematical model of the functioning of an optical fiber resonance piezoelectroluminescent (RPEL) sensor with an external nonlinear elastic buffer layer has been developed. The sensor is designed to measure the distribution spectrum along the length of the dynamic and/or static pressure sensor using a resonant diagnostic method based on the results of measuring the amplitude spectrum of the intensity of the resulting light flux at the output from the fiber of the sensor. The numerical values of the frequency characteristics (- these are the proportionality coefficients for the informative relationship "pressure/resonance frequency") of the optical fiber RPEL sensor, which are used in the algorithm for finding the pressure spectrum, for different (first six) modes of vibration, are determined.
