Abstract

The design and the realization of a cost effective reflective polarimetric fiber optic thermometer are discussed for several applications. The temperature dependent birefringence of a polarization maintaining fiber is used to deduce the sensor head temperature from measured polarization intensities. Measurements from a fabricated and packaged prototype show that the sensor features a non-ambiguous temperature range of >160°C and an accuracy of ±2°C.
