| Abstract: | The basic principle and the sensing structure of a new type torsion sensor are proposed in this paper.The theoretical formulas of the torsion measurement are derived and the torsional angle of this sensor is linear to the center wavelength change of fiber Bragg grating.The torsion sensing has been realized technologically with the sensitivity 10.715 degree/nm in the range of the torsional angle between -40? and +40? |

| Keywords: | Fiber Bragg grating Sensor Torsion sensing Torsional angle |
