Optical fiber Bragg grating structure and apparatus of measuring deformation of structure and method thereof

摘要

The present invention relates to an optical fiber grating structure and a structure deformation measuring apparatus and method using the same, wherein the optical fiber grating structure is at least one installed on the support such that the support and the portion formed so that a plurality of gratings are spaced apart from each other can be supported in a curved pattern An optical fiber grid is provided. According to the optical fiber grating structure and the structure deformation measuring apparatus and method using the same, the optical fiber grating having a grating formed at equal intervals is structurally bent and supported to detect and change the amount of light corresponding to the deformation degree of the measurement object. It provides the advantage of being able to calculate physical quantities such as bending, stress, temperature, etc. for the object.
