摘要

Abstract

A novel concept for distributed fiber sensing has recently been introduced

in which the sensing fiber itself forms a laser cavity. This configuration yields a high-quality response that is largely independent of position

thereby enhancing measurement accuracy and acquisition speed

and opening new avenues towards higher-performance sensing technologies.
