The invention discloses a fiber bragg grating sensor with the good airtightness. The fiber bragg grating sensor includes a fiber bragg grating sensor body, a sealing shell sleeves the surface of the fiber bragg grating sensor body, an upper sealing ring is fixedly connected to the top of the sealing shell, the upper sealing ring sleeves the surface of the fiber bragg grating sensor body, and a lower sealing ring is fixedly connected to the bottom of the sealing shell. According to the fiber bragg grating sensor with the good airtightness, through cooperative use of the sealing shell, the uppersealing ring, the lower sealing ring, a dehumidification box, a drying agent, an opening hole, a shock absorption rod, a spring, a pressing plate, a sliding block, a sliding groove, a first sealing sleeve, a second sealing sleeve, a fixing block and a limiting plate, the problem of poor airtightness of traditional fiber bragg grating sensors is solved; the has the advantage of good airtightness,the service life of internal parts of the fiber bragg grating sensor is prolonged, normal use of users is facilitated, the convenience to the users is brought.
Description
technical field [0001] The invention relates to the technical field of grating optical fibers, in particular to an optical fiber grating sensor with good airtightness. Background technique [0002] Fiber Bragg 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 has the advantages of being able to embed smart materials, 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 fields of optical fiber communication and sensing. [0003] However, the traditional fiber grating sensor is not well sealed, and air and moisture can easily enter the interior of the fiber grating sensor, resulting in damage to the internal parts, which greatly shortens the service life of the internal parts of the fiber grating sensor, which is not conducive to the normal use of the user. ...
