[SPADnet] May 2011: SPADnet was selected as one of the exhibits showcased at the FET11 conference in Budapest, illustrating the transition from the MEGAFRAME FET Open project to ICT Photonics's SPADnet, and in general the evolution of single photon imaging over the last decade.

Abstract: Single Photon Imaging: from Dream to Reality   

"The MEGAFRAME project has designed a camera whose pixels can detect a single photon, and compute its time of arrival, a million times per second. The SPADnet project plans to translate the technology behind this achievement to a new generation of smart, CMOS-based large area networked image sensors, targeted at photon-starved biomedical applications. Take a look at recent prototypes of the system and interact with a single photon camera. You will also be able to see images of the various generations of single photon detectors, illustrating the development chain over the years"

Corresponding Poster:Timeline of representative single photon pixels and imager arrays as developed from 2003 to 2011*, and illustrative applications. Two trends can be clearly identified in the timeline: a) increased complexity (gradual integration of intelligence on chip and eventually in pixel) and number of pixels (vertical direction), b) move to more advanced technologies (horizontal direction). The development cycle when moving from one technology node to the next - design of individual pixels first, followed by more complex structures - is also clearly visible.

*Emphasis on developments by EPFL/TU Delft and Edinburgh IMNS, and applications by EPFL/TU Delft, Edinburgh IMNS, Edinburgh COSMIC and SPADnet/MEGAFRAME.
