Abstract
We theoretically and experimentally investigated the influences of the sensing and lead fiber length, the extinction ratio of the input polarizer, and the coherence properties of the light source on polarimetric temperature measurements. We have shown that there is a possibility to construct a simple and inexpensive fiber optic polarimetric thermometer for absolute temperature measurements by using a low extinction-ratio polarizer and a low-coherence source. An experimental temperature sensor for absolute temperature measurement that works in the range from 20 to 60°C has been produced.
