Optica Sensing Congress
In August, Jane Hodgkinson and Dan Francis travelled to Munich to attend the Optica Sensing congress. Dan presented work on the development of an external-cavity quantum cascade laser spectrometer and Jane chaired a session on gas sensing. The conference, held in the Munich Hilton Park hotel in Tivoli, featured a good mix of spectroscopy talks combined with other areas of optical sensing.

SPIE: Optical Metrology
SPIE’s Optical Metrology conference held in conjunction with the World of Photonics congress took place in June in Munich. Tom Charrett, Kieran Wiseman, and Sivaji Pillai attended and presented their work. They were joined in Bavaria by former colleague Thomas Kissinger, currently at TU Ilmenau, who was chairing a session on interferometric techniques at the conference.

EWOFS 2023
The European Workshop on Optical Fibre Sensors (EWOFS) was held at the University of Mons in Belgium from May 23rd to May 26th and is one of the major international events for the optical fibre sensors community. Steve James and James Barrington attended to present their work on range resolved interferometry in wind tunnel testing. Steve was also on the technical program committee and chaired one of the sessions.
