Paper Abstract

In this paper, the second-order sensitivities of the optical fiber sensor for simultaneous measurement of strain and temperature are analyzed theoretically and demonstrated experimentally for a dual-wavelength optical fiber sensor. Error analysis shows that such effects will be important when: (1) large strain (or temperature change) and small temperature change (or strain) are applied simultaneously; (2) large strain and large temperature change are applied simultaneously. But they can be omitted for small changes of the two parameters.
