What happens when a new technology is so precise that it operates on a scale beyond our characterization capabilities? For example, the lasers used at INRS produce ultrashort pulses in the femtosecond range (10-15 s), which is far too short to visualize. Although some measurements are possible, nothing beats a clear image, says INRS professor and ultrafast imaging specialist Jinyang Liang. He and his colleagues, led by Caltech's Lihong Wang, have developed what they call T-CUP: the world's fastest camera, capable of capturing 10 trillion (1013) frames per second (Fig. 1). This new camera literally makes it possible to freeze time to see phenomena—and even light—in extremely slow motion.
In recent years, the junction between innovations in non-linear optics and imaging has opened the door for new and highly efficient methods for microscopic analysis of dynamic phenomena in biology and physics. But harnessing the potential of these methods requires a way to record images in real time at a very short temporal resolution—in a single exposure.
Using current imaging techniques, measurements taken with ultrashort laser pulses must be repeated many times, which is appropriate for some types of inert samples, but impossible for other more fragile ones. For example, laser-engraved glass can tolerate only a single laser pulse, leaving less than a picosecond to capture the results. In such a case, the imaging technique must be able to capture the entire process in real time.
Compressed ultrafast photography (CUP) was a good starting point. At 100 billion frames per second, this method approached, but did not meet, the specifications required to integrate femtosecond lasers. To improve on the concept, the new T-CUP system was developed based on a femtosecond streak camera that also incorporates a data acquisition type used in applications such as tomography.

I expect that as with most technical innovations in the audio/video world, the porn industry will be the first to bring this to the mainstream.
On the topic, does anyone have a recommendation on an affordable camera with a high frame capture that might capture a bullet, for example? Best I've found is over $1,000. Budget is $500 and under.
Beat me to it. Every new tech breakthrough it seems is used to make porn faster to download/easier streaming/higher definition, etc.
What are the practical applications of a camera that captures this many frames per second?

Best guess is to capture light or possibly in a super collider to capture atomic collisions.
Reducing/eliminating the “uncertainty principle”?

That industry pioneered a lot of things.
If Mel Brooks were to re-shoot Blazing Saddles would this camera allow to actually see The Waco Kid draw his guns?
I don’t care how fast it is. My wife would still be in the middle of blinking her eyelids in every picture she asks me to take of her.
Get you mind out of the gutter! ;-) This is the type of thing that could be used,among other ways,in medical research!
“Get you mind out of the gutter! ;-)”
Hmm, perhaps not.
Maybe more than a “flash of light” could be captured at the moment of conception.
All kinds of interesting stock footage could be made as well.
Maybe the engineers among us could team up with neuroscientists to study how to better make robots.
How does the sensation of touch travel from pad of the thumb to the brain? What other areas are effected and for how long?
Do these areas establish a ‘memory’ of easier path of communication the next time this touch is felt by this thumb?
I think it was EG&G that developed a capacitive shutter really get the FPS up there.
I can see the new cameras being used in, say cavitation research, off the top of my head.
Then there's all the new materials being developed. It would be useful in see what's happening before a material fails.
How would you know that?
