The fiber grating demodulation host machine can perform real-time online monitoring, full-channel scanning and high response speed. The scanning laser source can reflect the spectrum of a specific waveband when encountering the fiber grating mainly by generating a light source, and the fiber grating demodulator judges the change of external quantity acting on the fiber grating according to the change of the reflected spectrum. The fiber grating is also the core of the fiber grating demodulator. The fiber grating demodulation host is a diffraction grating formed by axially and periodically modulating the refractive index of a fiber core of an optical fiber through a certain method, and is a passive filter device. The grating fiber has the advantages of small volume, low welding loss, compatibility with fiber, embedding of intelligent materials and the like, and the resonance wavelength of the grating fiber is sensitive to the changes of external environments such as temperature, strain, refractive index, concentration and the like, so the grating fiber is widely applied to the fields of fiber communication and sensing. The fiber grating demodulation host writes an incident light coherent field pattern into a fiber core by using the photosensitivity of a fiber material through an ultraviolet light exposure method, and generates a periodic variation of a refractive index in the axial direction of the fiber core in the fiber core, so that a spatial phase grating is formed. When one beam of broad spectrum light passes through the fiber grating, the wavelength meeting the fiber grating Bragg condition is reflected, and the rest of the wavelength is transmitted continuously through the fiber grating.
