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.
