Nobel prize to CCD sensot inventors

Press Release

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2009 with one half toCharles K. KaoStandard Telecommunication Laboratories, Harlow, UK, and Chinese University of Hong Kong “for groundbreaking achievements concerning the transmission of light in fibers for optical communication”

and the other half jointly to

Willard S. Boyle and George E. SmithBell Laboratories, Murray Hill, NJ, USA
“for the invention of an imaging semiconductor circuit – the CCD sensor” The masters of light

This year’s Nobel Prize in Physics is awarded for two scientific achievements that have helped to shape the foundations of today’s networked societies. They have created many practical innovations for everyday life and provided new tools for scientific exploration.

Digital images constitute the second part of the award. In 1969 Willard S. Boyle and George E. Smith invented the first successful imaging technology using a digital sensor, a CCD (Charge-Coupled Device). The CCD technology makes use of the photoelectric effect, as theorized by Albert Einstein and for which he was awarded the 1921 year’s Nobel Prize. By this effect, light is transformed into electric signals. The challenge when designing an image sensor was to gather and read out the signals in a large number of image points, pixels, in a short time.
The CCD is the digital camera’s electronic eye. It revolutionized photography, as light could now be captured electronically instead of on film. The digital form facilitates the processing and distribution of these images. CCD technology is also used in many medical applications, e.g. imaging the inside of the human body, both for diagnostics and for microsurgery.
Digital photography has become an irreplaceable tool in many fields of research. The CCD has provided new possibilities to visualize the previously unseen. It has given us crystal clear images of distant places in our universe as well as the depths of the oceans.
