Abstract

We analyze the second-order sensitivity effects of a polarimetric temperature sensor and a strain sensor. Such effects are shown to be important for a larger temperature change or strain and are demonstrated by the analysis of the errors between the experimentally measured data and the curves of linear and second-order polynomial regressions, respectively. It is also shown that for a small temperature change or strain, higher accurate values of the two parameters can be obtained only from linear regression. The cross-sensitivity effect is also studied experimentally.
