Scientists have created a blazing-fast scientific camera that shoots images at an encoding rate of 156.3 terahertz (THz) to individual pixels — equivalent to 156.3 trillion frames per second. Dubbed SCARF (swept-coded aperture real-time femtophotography), 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.

I was doing some napkin math for how many femtoseconds there are between each frame and how that compares to Planck time but this response does a better job capturing how cool this is.

I’m curious on your calculations nonetheless.

A femtosecond is 10^-15 seconds. Tera Hertz frequency is equivalent to a period length of 10^-12 second, a pikosecond.

So with 156 tera Hertz a frame is around 6.4 femtoseconds.

Planck time is around 10^-43, so still some way to go until we reach the clock speed of our universe :)

Hope I did that right!

I initially thought, “why would we need this,” but these two comments helped me readjust. I don’t need it but we’ll find a use for it.
