Abstract
Optical fiber sensors are becoming a prominent solution to perform shape sensing thanks to their interesting and well known advantages such as flexibility, lightweight, sensitivity, etc. However, the different approaches commonly used to
date, which include fiber Bragg gratings, OFDR or OTDR architectures, are not able to achieve a fully distributed and fast
performance over relatively long ranges (e.g., tens of meters) and with fine (cm-scale) resolution. Here, we present a novel
scheme to perform curvature sensing attaining all the previously mentioned features by application of time-expanded
phase-sensitive (TE-Φ)OTDR technology. TE-ΦOTDR is a promising distributed sensing technique that delivers a
performance ranging between that of OFDR and ΦOTDR. As a proof-of-concept, we interrogate three cores of a multicore
fiber (MCF) using TE-ΦOTDR, attaining curvature sensing with 10 cm resolution over a maximum measurable range of
125 m and a sampling rate of 50 Hz. The implementation of shape sensing schemes with the performance provided by TE ΦOTDR technology may open the door to new and interesting applications in civil engineering, medicine and seismology.
