Paper Abstract
This paper describes the principles and recent development of a new technique for measuring temperature and strain distribution using Brillouin backscattering rather than Rayleigh and Raman backscattering. The technique is based on temperature- and strain-induced changes in the Brillouin frequency shift. Experimental sensitivities of 1.2 MHz/K and 5.8 MHz/10-4 strain are demonstrated at a wavelength of 1.32 micrometers . Two approaches for measuring the weak Brillouin line are discussed.
