【摘要】 利用单模光纤的弯曲损耗特性,设计了基于光强调制的缠绕式光纤应变传感器,从不同缠绕直径、缠绕螺距和缠绕圈数三方面研究了其与传感器初始损耗的关系,得出了光纤初始损耗随光纤缠绕直径的增大、缠绕螺距的减小和缠绕圈数的增加而增大的结论。更多还原

【Abstract】 With the winding loss characters of single-mode fiber-optic,the winding fiber-optic strain sensor based on light intensity modulation is designed.And the fiber-optic initial loss in different winding diameters,winding pitches and cylinder numbers is researched.And then it got the conclusion that the initial loss can increase with the winding diameter enlargement,winding pitch reduction and cylinder number increment.更多还原
