New Ultrafast Camera Shoots Trillions of Frames Per Second to Reveal Micro-Events
-
Researchers in Canada created a new ultrafast camera called SCARF that can shoot up to 156.3 trillion frames per second, far faster than existing cameras.
-
SCARF uses a new method called passive femtosecond imaging and computational algorithms to capture spatial information by staggering light inputs in time.
-
SCARF was created to study micro-events that happen too quickly for current sensors, like semiconductor absorption and metal alloy demagnetization.
-
The breakthrough builds on previous work by the team's leader, Professor Jinyang Liang, a pioneer in ultrafast imaging.
-
Remarkably, SCARF was made using inexpensive off-the-shelf optical components rather than expensive customized parts.
