Background
The fiber grating sensor can realize direct measurement of physical quantities such as temperature, strain and the like. The wavelength of the fiber grating is sensitive to temperature and strain at the same time, namely the temperature and the strain simultaneously cause the coupling wavelength of the fiber grating to move, so that the temperature and the strain cannot be distinguished by measuring the coupling wavelength movement of the fiber grating. Therefore, the problem of cross sensitivity is solved, and the realization of the differential measurement of temperature and stress is the premise of the practical application of the sensor. The differential measurement of temperature and stress is achieved by determining the stress and temperature change by a certain technique. The basic principle of the technologies is that two or two sections of fiber gratings with different temperature and strain response sensitivity are utilized to form a double grating temperature and strain sensor, and the temperature and the strain are solved by utilizing 2 linear equations of two-dimensional system by determining the temperature and the strain response sensitivity coefficient of 2 fiber gratings. The differential measurement techniques can be broadly divided into two categories, i.e., multi-fiber grating measurements and single-fiber grating measurements.
