Bragg grating based nested fibre interferometers

open access: yesElectronics Letters, 1996
An approach to configuring multiple nested interferometric sensor elements, based on Michelson and Fabry-Perot interferometers in common fibres using Bragg gratings, is described. These configurations can be used to provide adaptive interferometric sensors which provide unique spatial sampling capabilities.

Recent Advances in Decoupling Strategies for Soft Sensors

open access: yesAdvanced Science, EarlyView.
This review provides an overview of recent advances in decoupling strategies for soft sensors. It summarizes single‐modal sensors that are insensitive to stretching, bending, crosstalk, and other environmental interferences, and highlights emerging multimodal decoupling methods enabled by spatiotemporal information and machine learning.

PRAXIS: a low background NIR spectrograph for fibre Bragg grating OH suppression

open access: yes, 2012
Fibre Bragg grating (FBG) OH suppression is capable of greatly reducing the bright sky background seen by near infrared spectrographs. By filtering out the airglow emission lines at high resolution before the light enters the spectrograph this technique ...

Applications of polymer optical fibre grating sensors to condition monitoring of textiles [PDF]

open access: yes, 2009
Fibre Bragg gratings (FBGs) in polymer optical fibres (POFs) have been used to measure the strain in a woven textile. FBGs in both POFs and silica optical fibres were attached to a woven textile specimen, and their performance characterised.

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection

open access: yesAdvanced Science, EarlyView.
Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.
