The invention relates to the technical field of fiber bragg grating strength detection, discloses a fiber bragg grating strength detection device, and aims to solve the problems that when an existing strength detection device is used, on one hand, actual detection on batch fiber bragg gratings is difficult in a reciprocating motion mode, the detection efficiency is limited, and on the other hand, the fiber bragg gratings are difficult to clamp. And the optical fibers are loosened in the detection process, detection errors easily exist, a transmission mechanism is installed in the supporting box, and clamping mechanisms which are symmetrically distributed are installed on the two sides of the interior of the detection table correspondingly. The detection pressing block and the pressure sensor can be driven to move up and down through the transmission mechanism, so that the strength of the fiber bragg grating main body below can be conveniently detected, the detection efficiency is greatly improved, the two sides of the fiber bragg grating main body can be clamped through the two symmetrically distributed clamping mechanisms, the loosening phenomenon of the fiber bragg grating main body in the detection process is prevented, and the detection accuracy is improved. Normal detection of the fiber grating main body is guaranteed, and detection errors are reduced.
Description
technical field [0001] The invention relates to the technical field of optical fiber grating intensity detection, in particular to an optical fiber grating intensity detection device. Background technique [0002] Fiber grating is a kind of diffraction grating formed by axial periodic modulation of the refractive index of the fiber core by a certain method. It is a passive filter device. Because the grating fiber has small , can be embedded in smart materials, etc., and its resonant wavelength is sensitive to changes in the external environment such as temperature, strain, refractive index, concentration, etc., so it has been widely used in the field of optical fiber communication and sensing. Fiber grating sensors are installed in In the process, the strength of the fiber grating needs to be detected, and fiber grating sensors with different strengths need to be used according to different installation environments. [0003] When the existing intensity detection device is ...
