Nano-displacement sensing based on an extrinsic hybrid fiber Fabry-Perot interferometer is
proposed and demonstrated. The lead-in fiber tip of such an interferometer consists of a …

We report a fringe visibility-enhanced extrinsic Fabry-Perot interferometer (EFPI) by fusion
splicing a quarter-pitch length of a graded-index fiber (GIF) to the lead-in single mode fiber …

We report on the use of a simple interferometer built with strongly-coupled core optical fiber
for accurate vibration sensing. Our multi-core fiber (MCF) is designed to mode match a …

In this paper, the principle of a self-calibrated non-contact fibre-optic Fabry–Perot
interferometric vibration displacement sensor (FOFPIVDS) system is described and …

This article presents an ultrasensitive open-ended hollow coaxial cable resonator (OE-
HCCR) that was trained to detect impact events that occurred in the surrounding space …

Resolution investigation of multiplexed displacement sensors based on extrinsic fiber Fabry–
Perot interferometers (EFPI) was carried out. The cases of serial and parallel configurations …

A compact micro-ball lens structure is fabricated at the cleaved tip of microfiber coupler
(MFC) waist for displacement sensor application. The MFC is made by fusing and tapering …

Interferometric optical fibre sensors have proved to be many orders of magnitude more
sensitive than their electrical counterparts, but they suffer from limitations in signal …

The fabrication, implementation, and evaluation of an in-fiber white-light interferometric
distance sensor that is capable of measuring the absolute value of an arbitrary small …

An analysis is provided of fiber-optic Fabry–Perot interferometers designed and fabricated
using collimating graded-index fiber (GIF) tips as an alternative to typical highly divergent …
