Measurement analysis of temperature and stress based on fiber Bragg grating

Abstract

Abstract:

A double-grating combination structure based on equi-intensity cantilever is adopted to achieve simultaneous measurement of temperature and stress. Selecting two fiber Bragg gratings of the same batch of production with consistent parameters, paste them. to the upper and lower beam surface, respectively. The upper and lower beam grating suffered from equivalent stress but in opposite direction, resulting in two reflection peaks to achieve the simultaneous measurement of temperature and stress. The measured grating temperature sensitivity coefficient is 0.1346nm/℃, the upper and lower beam raster error is only 0.0001nm/℃; the stress sensitivity coefficients were 0.4085nm/N,-0.4089nm/N, separately, errors are only 0.0004nm/N.The experiment result shows that the method is practical and have a simple craftsmanship, moreover, it overcome the traditional double-grating combination disadvantage that is difficult to ensure the accuracy of measuring position.

Key words: fiber and waveguide optics, dual-parameter measurement, fiber Bragg grating, temperature measurement, stress measurement, equi-intensity cantilever
