Abstract
This work has presented a compact fiber bending sensor by superimposing a uniform fiber Bragg grating (FBG) in a tilted fiber Bragg grating (TFBG). The band of light reflected by the FBG passes through the TFBG twice and is modulated by its transmission, which is sensitive to fiber bending. The applied bending on the sensor can be determined by monitoring the power changes of Bragg resonance of FBG. Experimental results show the proposed sensor is insensitive to ambient temperature changes.
