High-Precision Static Strain Field Measurement Based on Dense Fiber Bragg Grating Array
2023 Asia Communications and Photonics Conference/2023 International Photonics and Optoelectronics Meetings (ACP/POEM)（2023）
Abstract
We have achieved precise static strain field measurement and applied for 2D shape sensing by using DFBG array with 20 different wavelengths. The accuracy was high with
$\boldsymbol{0.83}\ \boldsymbol{\mu}\boldsymbol{\varepsilon}$
strain sensing and 0.2% reconstruction error.
