Abstract

A differential temperature sensor employing a low-coherence interferometry technique with signal processing based on phase scanning is described. The sensor is composed of a compensated interferometer formed by two sections of a high-birefringence fiber and a polarimetric scheme, which includes Wollaston prism and polarizer, permitting the interference between two orthogonally polarization modes. The sensor allows the measurements of the difference in temperature, between two points with high sensitivity. The sensor can be used in calorimetry for laser power measurements. The details of the sensor configuration and signal processing method along with experimental results are described.
