Paper Abstract

The Operating principle of Fiber Bragg Grating Strain Sensor is introduced. A new demodulation method, which is by making use of the linear decline section of an amplified spontaneous emission (ASE) light source, was propose for Fiber Bragg Grating (FBG) sensor. The setting is simple, broad measurement range, appropriate sensitivity and measurement of static and dynamic. We have measured the strain of the cantilever, got the linear relation between output voltage and axial strain of the cantilever. The output voltage and theoretical value is fitted very well.
