The Rosalind Franklin Institute has started the development of a 100 million fps high-speed camera that will operate at 1-megapixel resolution to scan how new cancer drug treatments along with ultrasound interact to create effective cures for the deadliest forms of the disease. This type of performance is unheard of in that resolution and would herald a new way of looking at minute amounts of time that happen so fast no detector so far has been able to capture them at a usable resolution.
To put this in numbers, the camera will be able to capture a 100,000,000,000,000 or One Hundred Trillion Pixels per second or one hundred million megapixels/sec. Those are staggering numbers and if saved in a raw format it would take a megabyte per frame or 100 Terabytes of imaging data/second. That will be one extremely large frame buffer. With compression techniques and image optimization you could probably get that number lower but if played back at 30fps it would take 38 days to see a single 1-second video, staggering speed for sure!
