The invention belongs to a detection device, and particularly relates to a correction device for detecting deformation of a fiber grating. Deformation is detected by a fiber grating sensor, so that deformationdetection technologies for members, concrete foundations, numerical control machine tools and the like are improved and developed.The device comprises a correcting device for correcting a fiber grating deformation detection sensor, wherein the correcting device comprises a support as well as a left fixing bracket, a right fixing bracket and a loading bracket which are mounted on the support; the deformation detection sensor is supported above the support through theleft fixing bracket and theright fixing bracket; the loading bracket is detachably connected with the support, a loadingpiece is arranged on theloading bracket, and is in contact with the deformation detection sensor to apply pressure to the deformation detection sensor; a plurality of displacement sensors are arrangedon the support in the len
