摘要：

The applications of Fabry-Perot (F-P) fiber-optic strain sensor based on white light interference are mainly restricted by the cross-sensitivity effects, which caused by the changes of the temperature and stress. In this paper, the sensing principles of the white light interference F-P fiber-optic strain sensor is briefly introduced, then the methods to eliminate or weaken the temperature sensitivity of is described. Based on studying the temperature compensation mechanism of F-P fiber-optic white light interferometer strain sensor, we will discuss from two aspects: the compensation of process and the compensation of measurement results. The temperature compensation method mentioned in this paper, can effectively removes the strain measurement error due to the temperature changes.
