Understanding the optics in our imaging fibres…..

If you make tiny imaging fibres with *ordered* core structure, does that impact how they image? We aimed to find out... nice work by Helen Parker: https://osapublishing.org/ol/fulltext.cfm?uri=ol-45-23-6490&id=444064 In Optics Letters. A reminder how we use these fibres for endoscopy: https://tanner-lab.org/2019/04/01/ratiometric-spectral-imaging-through-fibre-to-make-the-bacteria-shine/ https://www.osapublishing.org/boe/fulltext.cfm?uri=boe-10-4-1856&id=407395

Time resolved investigation of tiny fibre fluorescent probes (the ones we use to measure deep in the lung)

Great work from Katjana getting this time resolved spectroscopy paper out. https://doi.org/10.3390/s20216115 In MDPI Sensors We highly load fluorophores onto optical fibres for medical sensing, but when you pack in a lot of fluorophore the behaviour gets complex. How to investigate? We use our favourite technique, time resolved spectroscopy! Direct observation of the energy transfer …

I love the video in our new paper: Observing mode-dependent wavelength-to-time mapping in few-mode fibers using a single-photon detector array

My first fully online conference..... it worked well. I missed all the interaction and networking, but it was great to be able to dip into high quality talks in between home schooling..... we had a few talks, I hope people enjoyed them! https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TTu2B.4 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TM2B.5 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TW2B.2 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TTu2B.3 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TTu2B.2

A tiny fibre sensor for measuring conditions in the lung….

Very happy this is finally published, it's taken a while..... I think this work really well describes the combination of technologies across a collaboration to do something really nice (and it looks kind of cool!) A few of my notes on the content below:   High fidelity fibre-based physiological sensing deep in tissue Scientific Reports, …
