Paper Abstract

To solve the problem of cross sensitization when the strain and the temperature are measured at the same time, we propose a structure of a ditrigon cantilever beam of uniform strength, realize a sensor structure in which the strain and the temperature can measured at the same time by a single fiber grating. The beam is bended and elongate the grating sticked on the surface of the beam, the reflectance spectrum from the grating is splitted into a double-peak spectrum. The strain can be measured by the space of the double peak. The variation of temperature is converted into the whole displacement of the reflectance spectrum.
