Abstract

Principle of Raman-scattering based distributed optical fiber temperature sensor (DTS) system is introduced briefly in this paper. The reference temperature is an important factor to improve the measurement accuracy of the DTS system. An experimental method is presented to study the relationship between reference temperature and measurement accuracy. A temperature & humidity chamber is used to provide different reference temperatures. Experiment data show that the measurement deviation decreases when the reference temperature increases.
