Temperature Compensation of Fabry-Perot Optic Fiber Strain Sensors
The applications of (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. It is briefly introduced the sensing principles of the white light interference F-P fiber-optic strain sensor in this paper, 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, it is proposed by the compensation of process to do it. The temperature compensation method mentioned in this paper, can effectively removes the strain measurement error due to the temperature changes.
