Abstract	The applications of Fabry-Perot (F-P) fiber-optic white light interference strain sensor are mainly restricted by the cross-sensitivity effects of the cavity length changes, 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, used to measure the smart structure, is briefly introducted, then the methods to eliminate or weaken the temperature sensitivity of is described. The temperature compensation formula and project implementation are presented during the fiber-optic strain measurement. The temperature compensation method mentioned in this paper, can effectively removes the strain measurement error due to the temperature changes.
