Abstract

A multi-parameter sensor for distributed measurement of temperature and strain based on Brillouin scattering in dispersion-shifted fiber is proposed, which is an excellent candidate for the cross effects in traditional Brillouin sensing system. In experiment, a temperature accuracy of 2 ℃, a strain accuracy of 60 με are achieved simultaneously.
