Excellent work from Eunan on this... maximising on the advantages of a line sensor for TCSPC (photon counting), but using it for imaging. I recommend the videos. Now Published in Optics Express. https://doi.org/10.1364/OE.461334 (videos in supplementary...) https://twitter.com/i/status/1560555107737018370 https://widgets.figshare.com/articles/19619631/embed?show_title=1
Excellent to get to something real, meet nice people, and get the chance to present our work...... (links to talks below) Weather was OK too: Talks be Eunan and Helen: Time-Correlated Single-Photon Counting Imaging to Locate Fibre-Optic Medical Devices Deep-in-Tissuehttps://doi.org/10.1364/TRANSLATIONAL.2022.TW1B.5 Selective Plane Illumination Fluorescence Endomicroscopy using a Polymer Imaging Fiber and an End-caphttps://doi.org/10.1364/TRANSLATIONAL.2022.TW1B.6
Great to see excellent speakers for this (and some in expert chairing by me). It was fun to organise, and well done to all for engaging in the continuing online format.... https://www.iopconferences.org/iop/frontend/reg/tOtherPage.csp?pageID=1088999&eventID=1764 Whole thing is recorded here: https://www.youtube.com/watch?v=LY4i5cx_5bU
This is fun, making a single multi-core fibre have lots of bright points along it, that we can turn on one at a time.Hari spent lots of effort trying to get these emitting fairly evenly. I think this might be really useful for medical sensing through the length of a human organ (see text below), …
It was a lot of fun organising this, and exciting to see how advanced technologies can get applied to real challenges. Hoping we can do something in person like this soon.... http://iqt2021.iopconfs.org/home
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
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 …
A large long running collaborative effort on this one.... https://doi.org/10.1007/s00259-020-05021-4 Observing the presence of bacteria through our custom made fibre endoscope (the one mentioned in other posts).Optics, biology, clinicians.... it's all there.
