Comparison of the methods for discriminating temperature and strain in spontaneous Brillouin-based distributed sensors

Opt Lett. 2004 Jan 1;29(1):26-8. doi: 10.1364/ol.29.000026.

Abstract

A recently proposed method of measuring the two Brillouin frequencies in a multicompositional fiber core for unambiguously resolving temperature and strain in a distributed sensor is compared with the previously established technique of measuring the intensity and frequency of the single Brillouin peak in a standard single-mode fiber.
