摘要
报道了一种新型光纤光栅扭转传感器的基本原理和传感结构 ,推导了扭转测量的理论公式 ,该传感器的扭角与光纤光栅中心波长的变化呈线性关系 .在± 40°扭角范围内 ,技术上实现了灵敏度为 1 0 .71 5°/nm的扭转传感 .
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°
