description: The purpose of the work is to develop a physical and mathematical model of the system and to identify violations of the demodulation of the signals of the export-optical Fabry-Perot interferometer interrogated using a spectral interrogation system, and instability in frequency changes over time. As a result of this work, an experimental law of deformation of a piezoceramic element was obtained with recalculation in the law of frequency tuning versus time. With the help of the developed model, using the proposed algorithm, the discrepancy between the restored and the specified specific frequency change, the demodulation errors of the FPPI signal for different parameters of systems and post-processing blocks was investigated. The novelty of this work is determined in the schemes for monitoring frequency fluctuations, due to measurements of elevated photodetectors and ADC manifestations for post-processing using the proposed algorithm for measuring frequency fluctuations.
