Optical Fibre Sensors: Lausanne 2018

In September, Antonio Rendon-Romero, Jonathan Hallam, and Steve James travelled to Switzerland to attend the 26th International Conference on Optical Fibre Sensors. Antonio presented a poster on his work on fibre Bragg grating immunosensors and Jonathan delivered a talk on the use of single-mode optical fibres in optical coherence tomography.

Young Researchers' Futures meeting: Edinburgh 2018

In September, Jonathan Hallam returned to Edinburgh to attend the Royal Academy of Engineering's Young Researchers' Futures meeting. Organised by the Academy’s panel for Biomedical Engineering, this biennial, multi-disciplinary event provides a forum for the best young engineers and scientists from throughout the UK. Jonathan presented his work on high-speed microfluidic particle velocimetry using optical coherence tomography.

International Mass Spectrometry: Florence 2018

In August, Célia Lourenço travelled to Florence to attend the 22nd International Mass Spectrometry Conference. Célia presented two posters covering both her PhD research on mass spectrometry as well as her recent work investigating the volatile constituent of composite materials at elevated temperatures. The conference was held at the historic "Fortezza da Basso", a masterpiece of Renaissance military architecture, built in 1534-1537, fully restored and located downtown, a few steps away from many hotels and all the attractions (museums, theatres, monuments, etc) of the city.

CIRP ISME: Ischia 2018

In July, Tom Charrett visited Ischia in the Bay of Naples to attend the CIRP Intelligent  Computation in Manufacturing Engineering conference. He presented work on the development of a positioning sensor that combines speckle correlation metrology with range-resolved interferometry. The main scope of the Conference was to provide an international forum for the exchange of the knowledge, information, experience and results as well as the review of progress and discussion on the state-of-the-art and future trends in intelligent computation methods and tools applied to manufacturing processes and systems.

Lisbon International Symposium 2018

In July, Jonathan Hallam visited Lisbon to attend the 19th edition of the International Symposium on Applications of Laser and Imaging Techniques to Fluid Mechanics. Internationally known simply as the LISBON SYMPOSIA, the event gives the opportunity for researchers and industries to connect and share new advances in laser and imaging techniques for thermo-fluid-dynamics studies, as well as the latest applications in the field. Jonathan presented his work on the use of optical coherence tomography in particle tracking velocimetry.

ETTC: Nuremburg 2018

In June, Erica Alcusa Sáez and Steve James travelled to Nuremburg, Germany to present their work on fibre-optic measurements in wind tunnels at the European Test and Telemetry conference.  The conference provides a forum for the discussion of telemetry technologies for aeronautical, space, automotive, biomedical applications.

Eurobrake: Den Haag 2018

In May, Steve James attended the EuroBrake conference in Den Haag, The Netherlands. He presented work on optical measurements of brake pad pressure distributions. EuroBrake forum was created in 2012 to address the profound changes in the demands made by the braking industry’s customers and end-users, and to provide a forum for companies and engineers working in the area of brake technology to come together to share ideas.

Photonics Europe 2018: Strasbourg

In April, Jane and Dan attended the SPIE Photonics Europe conference in Strasbourg, capital of the Alsace-Lorraine region and centre of the European Parliament. The conference is the largest of its kind in Europe covering  the most significant photonics technologies—from digital optics to quantum technologies to attosecond science.

Jane had an invited presentation on her work on the use of integrating spheres as gas cells and Dan presented recent work on refractive index measurement using low-coherence interferometry. Both talks were in the Optical Sensing and Detection conference. The talks went well and were well attended even though they were at awkward times - Jane was at 8:30 in the morning and Dan was in the afternoon of the last day!
