Scientists have created a blazing-fast scientific camera that shoots images at an encoding rate of 156.3 terahertz to individual pixels — equivalent to 156.3 trillion frames per second. Dubbed SCARF , the research-grade camera could lead to breakthroughs in fields studying micro-events that come and go too quickly for today’s most expensive scientific sensors.
SCARF has successfully captured ultrafast events like absorption in a semiconductor and the demagnetization of a metal alloy. The research could open new frontiers in areas as diverse as shock wave mechanics or developing more effective medicine.of Canada’s Institut national de la recherche scientifique . He’s a globally recognized pioneer in ultrafast photography who built on his breakthroughs from a separate study six years ago.
In extremely simplified terms, that means the camera uses a computational imaging modality to capture spatial information by letting light enter its sensor at slightly different times. Not having to process the spatial data at the moment is part of what frees the camera to capture those extremely quick “chirped” laser pulses at up to 156.3 trillion times per second.
Remarkably, it did so “using off-the-shelf and passive optical components,” as the paper describes. The team describes SCARF as low-cost with low power consumption and high measurement quality compared to existing techniques. Although SCARF is focused more on research than consumers, the team is already working with two companies, Axis Photonique and Few-Cycle, to develop commercial versions, presumably for peers at other higher learning or scientific institutions.
