Abstract

The invention discloses a fiber grating inclination sensor made of all glass, which comprises a glass cover, a glass cylinder, a glass block, a cross glass rod, an equal-strength tempered glass beam, a first fiber grating, and a second fiber grating; the glass cylinder The inner wall of the upper part is provided with an internal thread, which is connected with the external thread of the cylindrical surface of the glass cover to form a closed space; the equal-strength tempered glass beam is fixed on the glass cover, and the cross glass rod is fixed on an equal-strength tempered glass rod. Below the glass beam, the glass block is fixed on the lower end of the cross glass rod; the first fiber grating and the second fiber grating are fixed on the surface of the equal-strength tempered glass beam, and the tails of the first fiber grating and the second fiber grating The optical fiber at the end is led out from the optical fiber access hole of the glass cover. The invention solves the problems of low sensitivity, complex structure and long measurement time of the existing inclination sensor, prolongs the service life of the sensor and has wide application range.

Description

technical field [0001] The invention belongs to the technical field of sensors and relates to optical fiber sensing technology, in particular to a fiber grating inclination sensor made of all glass. Background technique [0002] With the continuous development of detection methods, in addition to the conventional measurement of physical quantities such as temperature, pressure and acceleration, more and more occasions need to measure the tilt state of objects; in some engineering construction, there are still many measurement problems to be solved urgently, and Deformation monitoring of engineering structures and angle measurement of structures are also very important aspects. Therefore, this requires inclination sensors to detect. Inclination sensors are used to measure the angular deflection of an object relative to a reference plane or datum line. They are also often used in large-scale infrastructure such as aviation (such as monitoring the attitude of an aircraft landi...
