Current Status of Research on Temperature and Strain Cross-sensitivity of Fiber Bragg Grating Sensors
光纤光栅传感器温度和应变交叉敏感的研究现状

In this paper,two methods for differentiating between the strain and temperature measured by a fiber grating sensor:the dual-wavelength matrix method and the dual-parameter matrix method are presented in the aspects of measurement principle and experiment equipment.Their main operation principles are described,their diagrams are given and their advantages and disadvantages are compared with each other.Thus,the reference is provided for the selecion of proper measurement methods in the future.
