Chen, Xianfeng F., Zhou, Kaiming, Suo, Rui, Zhang, Lin and Bennion, Ian (2006). In-fibre twist sensor based on TFBG structures. IN: Optical Fiber Sensors, OSA Technical Digest (CD). Optical Society of America.


We report a novel in-fibre twist sensor utilising strong polarisation dependent coupling behaviour of fiber Bragg grating with 81° tilted structure. The demonstrated twist sensor has shown high torsion sensitivity and capability of direction recognition.
