Abstract
The present disclosure provides a novel distributed coaxial cable strain sensor that can measure a strain profile over the entire length of a cable. Individual strain sensing elements are constructed using Fabry-Perot interferometers, coaxial cable Bragg gratings, or other reflectometry-based sensing structures. By assembling three or more strain sensors together in a bundle, a coaxial cable shape sensing device can be constructed which is capable of accurate three dimensional position measurement.
