Abstract

An optical fiber thermometer for electrical energy applications has been developed. The instrument uses the radiation of leaky modes in a short bend of standard singlemode fiber covered with polymeric resin, to sense temperature variations in the external medium. Suitable precision (<EQ +/- 2 degree(s)C) and good stability in the usable range of 5 degree(s)C - 170 degree(s)C are achieved.
