Abstract

The invention discloses a high-rate fiber grating demodulating instrument comprising a box body. A circuit connecting board is arranged between two sides of the inner wall of the box body. An opticalpath unit, a broadband light source, an adjustable F-P filter, and a fiber grating sensing module are arranged at the top of the circuit connecting board successively from left to right and are connected in series. First arc plates are fixedly connected between the two sides of the bottom of the inner wall of the box body and the two sides of the inner wall. According to the invention, a micro fanis started to carry out blowing and cooling; after cooling, limiting is performed by the first arc plates, a second arc plate, a third arc plate, and a partition board; after cooling by a first cooling block and a second cooling block, the fiber grating demodulating instrument can work at a proper working temperature, so that the fiber grating demodulating instrument can carry out transmission ata high speed. The instrument can be used conveniently; and unnecessary losses can be reduced.

Description

technical field [0001] The invention relates to a fiber grating demodulator, in particular to a high-speed fiber grating demodulator. Background technique [0002] A fiber grating is a diffraction grating formed by periodically modulating the refractive index of the fiber core in a certain way, and is a passive filter device. Because the grating fiber has the advantages of small size, small fusion loss, full compatibility with optical fiber, and can be embedded in smart materials, and its resonant wavelength is sensitive to changes in the external environment such as temperature, strain, refractive index, and concentration, it is used in optical fiber communication and The field of sensing has been widely used. [0003] The fiber grating demodulator is a relatively important high-precision instrument, but the existing fiber grating demodulator does not have a heat dissipation function when used, resulting in frequent jamming when using it, which is very inconvenient to use ...
