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.

Say “Ch-e-e-e-e-s-e!”
Interesting way to core an apple.
Unfortunately, it takes a long time to load the twenty-five MILES of film.
Great. The cliché used to be nanosecond. Now, it will be femtosecond.
Article about cameras and pictures but has no pictures?
“This is the type of thing that could be used,among other ways,in medical research!”
YEAH! For example, we may be able to locate the elusive G-spot with it. One step closer to understanding women!
World’s fastest camera freezes time at 10 trillion frames per second yet Bigfoot and UFO’s and aliens are still blurry when their photos are taken!!
bfl
So I take it that I’ll now need a separate hard drive for every minute of video.
It’s kind of an open secret in the tech industry.
Porn merchants are flush with cash and tend to become
the early adopters of new technology.
What are the practical applications of a camera that captures this many frames per second?
= = =
Will increase the demand for large storage devices ($).
Porn?
Would certainly clarify in/out on tennis court, touchdowns, fumbles, out or safe for baseball, goal for soccer, hockey. Ball/strike!
The uses are endless!
Hanging chad Yes/No?
MAGA!
Back in the late 40s Edgerton, Germeshausen, and Grier, Inc. created cameras that could take millions of frames per second. They were used to photograph our nuclear tests. We also used them during conventional weapons testing.
There are all sorts of applications in the world of science and physics that could use such cameras.
Damn it, your eyes are closed again!
Quantum physics is not my area, but I wonder if a camera that can take 10 trillion frames per second (that's 1e13 frames per sec) could see individual atomic particles or photons/light waves moving at speed of light (ONLY ~3e8 meters per sec).
The new camera is pretty fast in taking a picture in 0.1 picoseconds.
But that is still inadequately too long when trying to take a picture of an isolated moment during which a Demonicrat is telling the truth.
Quantum physicists have hypothesized such a moment might be less than 1 unit of Planck time.
We can finally see how fast the icebergs are melting and sea rising!
There’s a possibility that this camera could see Elizabeth Warren’s American Indian heritage, it’s so fast.
