Optical fibre nanowire sensors and applications

open access: yes, 2012
Optical fibre nanowires (OFN) have recently attracted increased attention because of their numerous applications in sensing and particle manipulation [1] and their extraordinary optical and mechanical properties, which include, amongst others ...

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Distributed optical fibre acoustic sensors – future applications in audio and acoustics engineering

open access: yes, 2016
First successful experiments with optical fibre acoustic sensors were performed in 1970s by Bucaro et al.1 and Cole et al.2. Those and later developments were primarily concerned with point sensors which are equivalent to single microphone or a ...

Simultaneous laser vibrometry on multiple surfaces with a single beam system using range-resolved interferometry [PDF]

open access: yes, 2015
A novel range-resolved interferometric signal processing technique that uses sinusoidal optical frequency modulation is applied to multi-surface vibrometry, demonstrating simultaneous optical measurements of vibrations on two surfaces using a single ...

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Polarization-Independent Focusing Vortex Beam Generation Based on Ultra-Thin Spiral Diffractive Lens on Fiber End-Facet

open access: yesPhotonics
An ultra-thin spiral diffractive lens (SDL) was fabricated by using focused ion beam milling on a fiber end-facet coated with a 100 nm thick Au film. Focusing vortex beams (FVBs) were successfully excited by the SDLs due to the coherent superposition of ...

Near infrared spectroscopy for fibre based gas detection [PDF]

open access: yes, 2010
Gas sensing systems based on fibre optic linked near infra red absorption cells are potentially a flexible and effective tool for monitoring accumulations of hazardous and noxious gases in enclosed areas such as tunnels and mines.
