Fiber Bragg grating, with the inherent advantage, is the most promising candidate sensor to be applied to smart structure. Based on the principle and technique in optical fiber communication, a method of dense wavelength displacement quantity with DWDM in optical fiber sensor system of smart structure was discussed. Experimental study and explanation were presented. The experimental results indicate that the Bragg wavelength of optical fiber grating is linear with its axial strain under definite surrounding temperature, which sets the foundations for boosting the application of optical fiber smart structure.
