Progresses and applications of f iber grating sensor

The recent research progress of optical fiber sensor was reviewed in this paper.Based on the wide application requirements,the researches of optical fiber sensors mainly focus on four fields:(1)transverse strain optical fiber sensor;(2)high sensitivity and high resolution fiber sensor;(3)low cast and high sensitive detection technology;(4)the most active filed is practical application technology of fiber sensors,including package technique,temperature compesation technique and sensors network technology.
