MICRO-VIBRATION OR DISPLACEMENT MEASUREMENT BASED ON A NOVEL BRAGG GRATING PAIR
Micro-vibration or displacement measurement is very important in modern industrial fields, especially for the micro electrical and mechanical system (MEMS). An optical fiber sensor was proposed to measure the micro-vibration or displacement based on a novel fiber Bragg grating pair, in which one of the gratings is written in the fiber cladding. The special reflection spectrum of the fiber Bragg grating pair is used,resulting in a high measurement sensitivity. Theoretical analysis of the fiber Bragg grating pair and micro-vibration or displacement measurement principle with the experimental setup are introduced in this paper.
