Better Biomedical Optics

Posted December 15, 2010 8:30 AM by Steve Melito

Frames per second (fps) is the rate at which consecutive images are displayed. Because the human brain perceives a rapid succession of still frames as motion, cameras with a higher fps produce smoother video. Until recently, these so-called "fast cameras" were used mainly by scientists and the television and movie industries. Thanks to the efforts of a European consortium, however, fast cameras may have a brighter future in cellular imaging and microarray scanning.

Developed by researchers from the U.K.'s National Physical Laboratory (NPL), ST Microelectronics, the University of Edinburgh, and TU Delft, the Megaframe Imager is an ultra-fast camera that records as many as one-million frames per second. Measuring just a few millimeters (mm), it uses complementary metal-oxide semiconductor (CMOS) technology to combine a super-sensitive single-photon avalanche diode (SPAD) array with on-chip intelligence.

Already, researchers have used the Megaframe Imager and fluorescence lifetime imaging to detect viral DNA binding events with a data acquisition time of 30 seconds. Is this ultra-fast camera the next big thing in biosensing?

The medical testing possibilities interest me in terms of glucose monitoring(unfortunately). Nice find.

According to
http://www.megaframe.eu/index.php?option=com_content&task=view&id=5&Itemid=28

the chip is a 128 x 128 pixel array taking 1 million images a second, so generates data at a rate of over 16 Gbits/sec. I hope there is plenty of fast local memory.
