Abstract

We demonstrate a fiber specklegram sensor based on the twist-induced effect in tilted two-mode fiber Bragg gratings (TM-FBGs). The measured LP21 mode specklegram rotates 4.73 (radm⁻¹) with twist in the tilted TM-FBGs.

基于倾斜双模光纤光栅扭致效应的光纤散斑传感器

我们展示了一种基于倾斜双模光纤布拉格光栅(tm - fbg)扭曲诱导效应的光纤散斑传感器。在倾斜的tm - fbg中，测量到的LP21模式散斑图随扭曲旋转4.73 (radm−1)。
