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 phenomenaand even lightin 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 resolutionin 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.

Wang "We knew that by using only a femtosecond streak camera, the image quality would be limited," says Professor Lihong Wang, the Bren Professor of Medial Engineering and Electrical Engineering at Caltech and the Director of Caltech Optical Imaging Laboratory (COIL). "So to improve this, we added another camera that acquires a static image. Combined with the image acquired by the femtosecond streak camera, we can use what is called a Radon transformation to obtain high-quality images while recording ten trillion frames per second."
Setting the world record for real-time imaging speed, T-CUP can power a new generation of microscopes for biomedical, materials science, and other applications. This camera represents a fundamental shift, making it possible to analyze interactions between light and matter at an unparalleled temporal resolution.
The first time it was used, the ultrafast camera broke new ground by capturing the temporal focusing of a single femtosecond laser pulse in real time (Fig. 2). This process was recorded in 25 frames taken at an interval of 400 femtoseconds and detailed the light pulse's shape, intensity, and angle of inclination.
"It's an achievement in itself," says Jinyang Liang, the leading author of this work, who was an engineer in COIL when the research was conducted, "but we already see possibilities for increasing the speed to up to one quadrillion (10 exp 15) frames per second!" Speeds like that are sure to offer insight into as-yet undetectable secrets of the interactions between light and matter.

Thats dividing a second into 10,000 billion pieces, or 10,000 x 1,000 million pieces.
In scientific notation, that's 10^-13.
Still, its not even close to the Plank Time(5.39 × 10^-44).
In quantum mechanics, the Planck time (tP) is the unit of time in the system of natural units known as Planck units. A Planck unit is the time required for light to travel in a vacuum a distance of 1 Planck length, which is approximately 5.39 × 10^-44 s.[1] The unit is named after Max Planck, who was the first to propose it.
The Planck time is defined as:[2]
The fastest time ever recorded was the time between the light turning green and the idiot behind you is on his horn. /s
I want one in a dslr body.
Technology continues to accelerate its advance.
Between that and the 24 hour news cycle people are having a lot of mental problems.
That’s like really really really really really really really really really fast.
Jinyang Liang. He and his colleagues, led by Caltech’s Lihong Wang,
So China already has this tech then...
...wanna see it again?
does Walgreens carry film for that camera....would it be like 616 or 532??
But then you still have to wait a week before the prints are ready at the drugstore.
Apparently still not fast enough to capture enough evidenc of Democrat corruption to bring them to trial.
Einstein says I can freeze that image in a billionth of a second.
Tesla says I can freeze that image in a trillionth of a second.
Edison says I can freeze that image in a quadrillionth of a second.
Albert and Nikolai turn to Edison and say "Thomas freeze that image"
Thats amazing. Years ago, I worked on weapons ranges where our high-speed video was 120k per second. That was fast enough to watch the spark of ignition on a block of C-4, see the blast wave propagate, hit the ground and bounce upward.
This advance is equivalent to moving from driving an oxen to riding a rocket. The possible applications are staggering.
Angels do their thing in between frames.
I would like to see similar work done with audio, so we can hear the pattern of a spider’s walk. Is it perfect 1/8 time?
. ..like Clint said... ”a man has to know his limitations”
But then you still have to wait a week before the prints are ready at the drugstore.
Sure, just choose from the billion prints.
I suppose you could get wallet size...
Sort of like a photo story in DailyMail. /sarc
I don’t get it. Help?
The Planck Epoch is that period from the Big Bang until the time passed was equal to the Planck time. I refer to everything before one Planck unit as God.
There used to be a TV show called “Name That Tune”.
Contestants would Say I can name that tune in 7 Notes, the other would say 6 on and on.
The person with the lowest bid of notes would get the chance to name the song in x number of notes and win prizes.
Only old farts get it.
