This year the FLAIR conference (Field Laser Applications in Industry and Research) returned to the French spa town of Aix-les-Bains. Nick Davis and Dan Francis attended to present posters on their recent work on tuneable laser spectroscopy. The posters, which only just arrived in the nick of time due to issues with UK delivery companies, were very well received.
The much anticipated social events included a five course conference dinner in the Aix-les-Bains casino and an excursion to Chateau de Montrottier, a 13th Century Savoyard castle. The visit to the chateau included a treasure hunt, a dinner that included a cheese fondue, and was followed by a live rock band.

Photon is the UK’s leading optics and photonics conference and this year’s edition was held at the East Midlands Conference Centre in Nottingham. Engineering Photonics was represented by Tom Charrett and Kieran Wiseman who gave talks on their recent work.
Tom, who had an invited presentation, discussed the development of optical instrumentation for process monitoring in additive manufacturing, and Kieran presented his work on high accuracy interferometric displacement sensors.

Covid-19: A lockdown retrospective
On Monday 23rd March 2020, the Engineering Photonics labs were closed with immediate effect due to the spread of COVID-19 that had originated in Wuhan four months earlier. Most EP staff were working from home from that point on until early April when most Cranfield staff were put on furlough. Furlough was done on a rota basis with everyone in the University being assigned a team: red, blue, purple, or orange.
In mid-June 2020, the EP labs were one of the guinea pigs, being one of the first in the University to re-open. The re-opening came with a host of safety procedures including a maintained rota system, use of hand-sanitizers and face masks, maintaining a social distance of at least 2 m, only one person to a lab, and regular cleaning of shared equipment. Mirrors were installed in the corridors to avoid contact with others passing by, and the white board was used with magnetic tokens to check in and out so that everyone knew who was present.
The alpha variant emerged in Kent at the end of 2020 and precipitated the third national lockdown in December. Whilst the labs remained open, access was more restricted with only essential work authorized. The period of managed access combined with intermittent furlough, known internally as ‘amber days’, lasted until around June 2021. By this time vaccines had been rolled out to more of the population and the COVID restrictions began to ease, eventually leading to a hybrid working scheme where staff continued to work a proportion of their time at home. Following the pilot phase the hybrid scheme continues to remain in place.
PhD viva success!
Congratulations to Kieran Wiseman who successfully defended his thesis on wavelength modulation interferometry for precision metrology!

Engineering Photonics bids farewell to James Bremner
The Engineering Photonics Group bids farewell to James Bremner who is leaving to join the Department of Electrical and Electronic Engineering at City University, London.
Members of the group who were present took the opportunity to say goodbye over a beer at the Cranfield Student Association bar.
