Abstract

The invention discloses a multi-channel high-speed fiber bragg grating demodulation device which comprises an insulating shell, a belt wheel set bin is arranged in the insulating shell, a driving roller and four driven rollers are fixed in the belt wheel set bin through shafts, and a conveying belt is connected between the outer surface of the driving roller and the outer surfaces of the four driven rollers. Strip-shaped grooves are evenly formed in the surface of the conveying belt, and strip-shaped magnets are fixedly arranged on the bottom faces of the strip-shaped grooves. A long channel located on the upper end face of the insulating shell is arranged above the conveying belt, a wedge-shaped slope is fixedly arranged at one end of the long channel, and the long channel comprises ten working butt joint grooves and a to-be-placed containing groove. Fiber bragg gratings can be arranged in a targeted mode for multi-channel optical fibers to be adjusted, and corresponding fiber bragg grating replacement operation can be carried out integrally and conveniently. The operation is convenient.

Description

technical field [0001] The invention relates to the technical field of fiber grating demodulation, in particular to a multi-channel high-speed fiber grating demodulation device. Background technique [0002] With the rapid development of social economy, the application of optical fiber is more and more extensive. The signal mediation of fiber Bragg grating is one of the main applications of fiber Bragg grating. From the perspective of the mediated light wave signal, the adjustment scheme of fiber grating sensing signal includes intensity mediation, Phase modulation, frequency modulation, polarization modulation and wavelength modulation, etc. [0003] However, the existing multi-channel fiber grating adjustment device has a simple structure and cannot be easily replaced for a single fiber grating; therefore, it does not meet the existing needs, and we propose a multi-channel high-speed fiber grating solution. tuning device. Contents of the invention [0004] The purpose ...
