Renato Turchetta Rutherford Appleton Laboratory on ultra-high speed imaging

Conference Producer Rob Stead speaks to Dr Renato Turchetta from Rutherford Appleton Laboratory in the lead up to his workshop at Image Sensors 2014.

Q. Firstly, thanks for pulling this session together. Why do you think it's the right time to run a workshop on ultra-high speed imaging?

"Up until a couple of years ago, ultra-high speed imaging devices were developed by a few groups only and progress was slow. Sensors were exclusively CCD. The landscape has recently changed with the introduction of two new CMOS sensors based on different concepts and capable of taking pictures at millions of frames per second. It looks like this field has suddenly started to move rapidly, so it wouldn't be unreasonable to expect more developments in the near future. By the way, one of the new approaches uses CCD in CMOS and other applications are emerging for this 'new' technology. So are CMOS image sensors dinosaurs? And CCD as well?

Q. Can you give us a quick rundown of what will be covered and why?

"Leading specialists in the field will help me covering all the main aspects of ultra-high speed imaging. Experts from Specialised Imaging, a UK company leader in the field, will give a short history of the field as well as covering aspects of the camera, like triggering, optics or light sources. They will also talk about some of the applications, together with Dr Paul Prentice from the University of Dundee, who would introduce the audience to the amazing world of bubbles, which are important in many fields, from cancer care to environment. The core of the workshop will be dedicated to the sensors, with Jan Bosiers covering CCD technology and myself covering CMOS sensors."

Q. Who should attend the workshop and what will they take away from the experience?

"Whoever is amazed by the high speed slow motions we can routinely see, for example, in sport events, should come and see how sensors and cameras are made to operate at even higher frame rates, beyond the barrier of a million frames per second. The audience will also learn about some of the applications for these sensors."

Q. You have attended the Image Sensors conference and presented a number of times, why do you think it's grown so well over the last few years and what makes it different from other meetings you attend?
 

"I think there are several factors in this. The variety of topics: each edition of the conference covers a great variety of subjects, from sensors for consumer applications to devices for scientific applications, going through other a variety of different applications, some well, some less known. Most of the speakers are renowned and experienced and engage with the audience at a variety of levels. Last, but not least, the networking offering of the conference is truly amazing. Over a few days, it is possible to meet with technical specialists as well as with potential customers and technology providers."
