s countries begin to ease lockdown restrictions, thoughts turn to how to get

the economy going again: how to get businesses operational, how to start manufacturing, and how to do all this safely. Termal imaging cameras to screen for signs of fever could help here, but how effective are they at doing this? Te article on page 12 addresses this question, while the article on page 4 has views from the heads of the AIA, EMVA, VDMA Machine Vision, and UKIVA on how the vision industry is being affected by the coronavirus pandemic. Also in this issue, Kieran Edge, at

the University of Sheffield’s Advanced Manufacturing Research Centre, describes on page 16 how his group is using polarisation imaging to inspect strands of carbon fibre as they are woven together to make composite components for aerospace and other high-value manufacturing. Matthew Dale on page 30 explores how different lighting regimes and computational imaging can be combined to bring out features in an image of a part that would otherwise be difficult to spot with standard illumination methods, while, on page 20, Keely Portway finds out how hospital testing labs are becoming automated to speed up analysis of samples. Finally, the article on page 24 looks

at how optical sensing can help process grain like wheat, maize or rice travelling through a Bühler machine at 10 tonnes per hour, optimising yield, and making the most of what is grown. Tis is important for tackling another, more gradual crisis looming on the horizon: climate change.
