Abstract

ABSTRACTThis work demonstrates the viability of using a cavity ring‐down (CRD) technique for remote sensing. A conventional CRD configuration is used where an optical circulator is added inside the fiber loop to couple 19 km of optical fiber with a gold mirror at its end with the purpose of remote sensing. As a proof‐of‐concept, an intensity sensor based on an eight‐figure configuration is used at the end of the 19 km of fiber for displacement sensing. © 2016 Wiley Periodicals, Inc.
