摘要：

A novel temperature-independent vibration sensor based on a fiber Bragg grating (FBG) is demonstrated. The FBG was glued in a slanted direction onto the lateral side of a right-angled triangle cantilever beam. Vertical vibration applied to the cantilever beam leads to a periodical variation of bending curvature along the beam length. As a result of beam bending, the FBG is chirped and its reflection bandwidth and optical power change with the deflection of the beam. Experimental results were compared with the data of vibration measurement of a conventional resistance strain gauge. Good agreement has been achieved. The sensor is temperature independent, owning to the temperature-independence nature of the reflection bandwidth and optical power of the FBG. (C) 2010 Wiley Periodicals, Inc.
