14 Dec 2012 The Bragg wavelength is sensitive to temperature and strain. This means that the FBGs can be used as sensing elements in optical sensors. This type of Fiber Bragg Grating is specially designed with narrow reflective bandwidth to allow for easy detection of center wavelength shifts.
It was widely used in bridge, petroleum tube and coal mine safety monitoring, river surveillance monitoring, civil structural monitoring, aerospace health monitoring etc.
Features:
High sensitive
High tensile strength and reliability
Strong ability of anti-electromagnetic interference
Easy to realize remote monitoring of the signal
Small size and weight
