Sensitivity Enhancement of Curvature Fiber Sensor Based on Polymer-Coated Capillary Hollow-Core Fiber

open access: yesSensors, 2020
In this paper, we propose and experimentally demonstrate a simple technique to enhance the curvature sensitivity of a bending fiber optic sensor based on anti-resonant reflecting optical waveguide (ARROW) guidance.

SnapShot: Membrane Curvature Sensors and Generators

open access: yesCell, 2012
Cells and intracellular organelles are enclosed by bilayer lipid membranes, whose curvatures define their shape. Generation of bilayer curvature is critical for organelle biogenesis and to mediate vectorial transport from one membrane to another via vesicular or tubular intermediates.

Angularly Cascaded Long-Period Fiber Grating for Curvature and Temperature Detection

open access: yesSensors, 2023
A high-sensitivity curvature sensor with dual-parameter measurement ability based on angularly cascaded long-period fiber grating (AC-LPFG) is proposed and experimentally demonstrated, which consists of two titled LPFGs (TLPFGs) with different tilt ...

Curvature sensors: noise and its propagation [PDF]

open access: yesJournal of the Optical Society of America A, 2010
The signal measured with a curvature sensor is here analyzed. In the outset, we derive the required minimum number of sensing elements at the pupil edges, in dependence on the total number of sensing elements. The distribution of the sensor signal is further characterized in terms of its mean, variance, kurtosis and skewness.

Curvature sensor for ocular wavefront measurement

open access: yesOptics Letters, 2006
We describe a new wavefront sensor for ocular aberration determination, based on the curvature sensing principle, which adapts the classical system used in astronomy for the living eye's measurements. The actual experimental setup is presented and designed following a process guided by computer simulations to adjust the design parameters for optimal ...

Hollow Core Bragg Fiber-Based Sensor for Simultaneous Measurement of Curvature and Temperature

open access: yesSensors, 2021
In this paper, the hollow core Bragg fiber (HCBF)-based sensor based on anti-resonant reflecting optical waveguide (ARROW) model is proposed and experimentally demonstrated for simultaneous measurement of curvature and temperature by simply sandwiching a

MARCKS-ED Peptide as a Curvature and Lipid Sensor [PDF]

open access: yesACS Chemical Biology, 2012
Membrane curvature and lipid composition regulates important biological processes within a cell. Currently, several proteins have been reported to sense and/or induce membrane curvatures, e.g., Synaptotagmin-1 and Amphiphysin. However, the large protein scaffold of these curvature sensors limits their applications in complex biological systems.

Research on Optical Fiber Sensor Based on Underwater Deformation Measurement

open access: yesSensors, 2019
With the increase in the scale and complexity of underwater engineering, safety problems caused by underwater deformation have become increasingly prominent. Although the intensity fiber curvature sensor can be used for curvature monitoring on the ground,
