Parameter optimization of a fiber optic birefringent temperature sensor with compensation configuration

Using numerical calculation methods, we have studied the relations among the key system parameters - the center wavelength, spectral width, crystal thickness, and their influence on the measurement accuracy, resolution, dynamic range, linearity. The optical parameters of the source and crystal are obtained, in the compensation configuration which can provide enough accuracy, resolution and stability. The theoretical and experimental methods proposed in this paper have important roles in other polarization-modulated fiber optic senors.
