Substrate-type packaged fiber grating sensor and application thereof

The invention discloses a substrate-type packaged fiber bragg grating sensor and application thereof, and belongs to the technical field of fiber sensing, the substrate-type packaged fiber bragg grating sensor comprises a fiber bragg grating body and fiber pigtails, the fiber pigtails are installed at the two ends of the fiber bragg grating body, and sheet-shaped substrates are installed at the bottoms of the fiber bragg grating body and the fiber pigtails. The top of the sheet-shaped substrate is provided with a groove matched with the fiber grating body and the optical fiber pigtail, and the groove is filled with epoxy resin. An outer protection mechanism is installed at the top of the sheet-shaped base plate, a bonding layer is installed in the outer protection mechanism, and an anti-impact mechanism is installed at the top of the outer protection mechanism and comprises a supporting frame, an inner arch bridge plate and an outer arch bridge plate. The temperature sensitivity of the fiber bragg grating bod
