In 2018, a research team at the INRS Universite De Recherche built the world fastest ever camera called T-CUP (Compressed Ultrafast Photography) doesn’t take your ordinary 2D photos. It is able to capture 10 trillion frames per second (fps)!

INNOVATION

Research and Development on ultra-fast camera in this past few years, T-CUP leaves them all in the dust.

This camera is used to record images in real time at a very short temporal resolution—in a single exposure (light per unit area). Now this technology helps scientists in many fields and open door to examine things like the nanoscale interaction between light and matter.

The team at INRS built this camera to capture events that operate at the Femtosecond range.

Because of femtosecond range operation, it is useful for capturing slow-motion imaging of things like laser pulses.

Of course, some measurements have been taken possible previously but nothing beats a clear image says INRS Professor and ultrafast imaging specialist Jinyang Liang.

The research team, led by Caltech’s Lihong Wang, put themselves to the task and developed this and set a new record-breaking camera which they have called T-CUP.

This new camera technology T-CUP literally makes it possible to freeze time to see phenomenon—and even light!—in extremely slow motion.

This type of device invaluable in other fields like microscopic research and observing dynamic phenomena in biology and physics.

T-CUP was built on existing technology called compressed ultrafast photography (CUP), a method that it is capable of 100 billion fps (frames per sec). That’s really very fast but not fast enough for INRS’s researchers. So they start working on T-CUP.

A femtosecond is 1 quadrillionth of a second FYI – that’s quick.

The team managed to combine a femtosecond streak camera with a static camera. Any images captured were then run through a technique called Radon transformation.

“We knew that by using only a femtosecond streak camera, the image quality would be limited” said Lihong Wang.

“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 10 trillion frames per second.”

Initial test results from the setup were really very inspiring. It was able to capture a single femtosecond pulse of laser light. It managed to record 25 images, each 400 femtoseconds apart.

Over the time, this level of accuracy was able to show changes in the light pulses shape. Intensity of laser and angle of inclination in much better detail than ever get before.

It’s an achievement in itself said Jinyang Liang, “But we already see possibilities for increasing the speed to up to one quadrillion frames per second!”
