Abstract

The article presents further development of radiophotonic sensor systems based on the usage of the addressed (AFBS) and multi-addressed fiber Bragg structures (MAFBS) as sensing elements. Addressed fiber Bragg structure is an emerging type of fiber Bragg grating, which has a spectral response with two or more narrow notches. The presented system comprises two optical filters with linear inclined frequency response, which are used simultaneously to determine the central wavelengths of the AFBSs or MAFBSs. This feature enhances the operating temperature range of the system and allows to simplify its implementation, since the necessity of temperature isolation of the optical filters is eliminated. The algorithm and the mathematical model for the thermal drift compensation of the optical filters are introduced, and their realization is discussed.
