One method to monitor the heating is MRI, which can map the temperature increase with high resolution, allowing optimisation of the ablation plan during the procedure4,12,13. However, the use of MRI is limited by the machine availability and high cost10. In addition, the low frame rate of...
A similar BOTDR based fibre optic strain sensing system was reported in a case study of a tunnel lining deformation induced by nearby construction in London [60]. For temperature compensation, separate loose tube optical cables were running along the tight buffed strain sensing cable in the tunnel...

Distributed optical fibre sensors deliver a map of a physical quantity along an optical fibre, providing a unique solution for health monitoring of targeted structures. Considerable developments over recent years have pushed conventional distributed sensors towards their ultimate performance, while any signif...
The fibre optic linked spectrometer 27a incorporates an array of pixel detector elements. The coherence length (Ici) of radiation incident on the ith pixel is given by I ci ≈ c Δ v i ≈ λ 0 i 2 Δλ i
All our home broadband packages are full fibre and utterly unlimited. And our pricing is fair and transparent (with no mid-contract price hikes) so you know what you’re paying upfront. Plus, if you find the same package being offered for less elsewhere, we promise tomatch it. ...

The clinical diagnostic evaluation of optic neuropathies relies on the analysis of the thickness of the retinal nerve fibre layer (RNFL) by optical coherence tomography (OCT). However, false positives and false negatives in the detection of RNFL abnormalities are common. Here we show that an algor...
