Fiber bragg grating temperature sensor based on 3D printing technology and assembly method thereof

The invention relates to the technical field of optical fiber temperature sensors, and specifically discloses a fiber bragg grating temperature sensor based on a 3D printing technology and an assemblymethod thereof. A fiber bragg grating in the fiber bragg grating temperature sensor is sleeved with a sensor housing formed through 3D printing. The fiber bragg grating temperature sensor based on the 3D printing technology and the assembly method thereof have the advantages that the sensing housing is printed by means of the 3D printing technology, on the basis of ensuring the measurement accuracy, the production cycle is greatly shortened, the manufacturing process is simpler, the cost is lower than that of traditional ceramic packaging sensor, stainless steel packaging sensor and the like,and the fiber bragg grating temperature sensor can be more widely applied and popularized in rock and soil geological engineering of mining, bridges, tunnels, slopes, roads and bridges and the like and physical model experime
