Miniaturized fibre‐top cantilevers on etched fibres [PDF]
Journal of Microscopy, 2016 SummaryFibre‐top probes are self‐aligned, all optical devices obtained by carving a cantilever on top of a 125‐m diameter single‐mode optical fibre. In this paper, we show that this design can be adapted to smaller fibres as well. We evaluated the performance of a 20‐m diameter probe in contact mode atomic force microscopy (AFM) and that of a 50‐m ...

A multiplexed CW Brillouin system for precise interrogation of a sensor array made from short discrete sections of optical fibre [PDF]
, 2008 A novel configuration for precise temperature sensing in an array of optical fibre sections is reported. The sections are chosen to have different Brillouin shifts, to enable separation of scattered light signals in the frequency domain, rather than the ...

Locally pressed fibre Bragg grating pressure sensor [PDF]
, 2006 A spectral-hole created by locally pressing a fibre Bragg grating exhibited a wavelength-shift within the FBG bandwidth. A sensitivity of 74.3pm/(N/mm) was obtained for pressure applied along the slow axis of a high birefringence ...

Predicting wood stiffness of lodgepole pine trees using acoustic tools and green density
The Forestry Chronicle, 2021 Upstream identification of wood properties using non-destructive testing methods such as acoustic velocity (AV) measurements is important for optimizing allocation of wood to mills or products. We evaluated the effectiveness of field AV measurement tools
