Abstract

Metallized fiber Bragg grating can improve bonding performance between metal material and fiber Bragg grating, protect the sensor, improve stability and prolong the lifespan of the sensor. The characteristics of temperature and strain of metallized fiber Bragg grating are studied in this paper. By using a thermostat, a good linearity of temperature characteristic of MFBG was achieved and its correlative coefficient reached 99.95%. A high precision displacement set driven by stepping motor was used to move the free end of the metal cantilever beam with uniform strength which was adopted to tune the metallized fiber Bragg grating, a good linearity was obtained, and its correlative coefficients was 99.96%.
