Bending loss is in the form of macrobending, and microbending is the type suitable in fiber optics sensors. Recently, various fiber bending sensors have been proposed to measure different physical
Clearly, TFCF is superior to the conventional tapered fiber coupler when serving as fiber bending sensors. In this work, the excitation of the asymmetric supermodes in the TFCF was
The theoretical analysis of the sensor, which is a combination of fiber coupled-mode theory and elastic-optic theory, validates the accuracy of the sensor. The sensor is also shown to be temperature
This study presents the design and performance analysis of a fiber optic bending sensor based on Single-mode–Multimode–Singlemode (SMS) structure, integrated wi
The bend loss principle and influencing factors of the fiber are analyzed, and the bending resistances of different fibers are discussed on the basis of theoretical and experimental comparisons.
In this paper, we propose a new fiber bending sensor based on speckle pattern imaging. The design and implementation of the sensor are demonstrated by simulated studies.
In this research, a novel optical torsion and bending dual-parameter sensor based on fiber specklegrams detection is proposed with a simple fiber structure, cheap detection device and
In this paper, we propose and demonstrate a deep learning-enhanced fiber specklegram sensor for bending recognition. A segment of multimode fiber is used to sense bending, and tiny
A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals
We develop and investigate fiber-optic bend sensor, which is formed by a section of double cladding SM630 fiber between standard SMF-28 fibers. The principle of operation of the sensor is based on
