Abstract

Three different techniques for simultaneous measurement of temperature and axial strain applied to a length of optical fiber are reviewed. It is shown theoretically that for large temperature change and high strain, the second-order effect becomes important. The experimental results for two different types of fibers are presented to verify the theoretical predictions, and the cross-sensitivity coefficients were measured.
