Shape Sensing Based on Dual-Comb Demodulation of a Fiber Bragg Grating Sensing Array
2022 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)（2022）
Abstract
A system for realizing shape sensing based on the single-cavity dual-comb spectroscopy technology and a dense all-identical fiber Bragg grating (FBG) sensor array is demonstrated. High spatial resolution and small measurement error can be realized with the proposed system, based on two-dimensional shaping sensing experiments. This scheme could find applications in real-time monitoring of flexible structures and facilitate the development of novel robotics and biomedical devices.
