& # 39; The world's fastest camera can see light in slow motion & # 39;



Researchers have developed what can be the world's fastest camera, which can capture 10 trillion images per second, allowing it to "freeze time" to see the light in extremely slow motion.

The difference can provide insight into -An undeniable secrets of the interaction between light and matter, according to researchers from the California Institute of Technology in the United States.

In recent years, the intersection of innovations in nonlinear optics and imaging has opened the door for new and highly effective methods for microscopic analysis of dynamic phenomena in biology and physics.

However, exploiting the potential of these methods requires a way to capture real-time images on a very short time resolution ̵

Using current image processing techniques, measurements taken with ultrasound laser pulses must be repeated many times, suitable for some types of inert samples, but impossible for others more fragile.

For example, laser engraved glass can tolerate just a single laser pulse, giving less than a picosecond to capture the results. In such cases, the picture 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 approach approached, but did not meet the specifications needed to integrate femtoseconds lasers.

In order to improve the concept, the new T-CUP system was developed based on a fifty-second broadcast camera that also incorporates a data collection type used in applications such as tomography.

"We knew that by using only a fifty-second band camera, image quality would be limited," said Lihong Wang, director of Caltech Optical Imaging Laboratory (COIL). [19659002] "In order to improve this, we added another camera that provides a static image. In combination with the image purchased from the fifty-second clip camera, we can use what is called a Radon transformation to provide high-quality images while you takes up tens of trillions of images per second, Wang said.

The position of the world-wide real-time image speed camera, the camera T-CUP, can drive a new generation of microscopes for biomedical, materials science and other applications.

This camera represents a basic shift, something which makes it possible to analyze the interaction between light and matter at an outstanding time resolution.

The first time it was used, the ultrafast camera broke new ground by capturing the temporal focus of a single five-hundred-second laser pulse in real time.

This process was recorded in 25 frames taken at a range of 400 femtoseconds and the detailed light pulse shape, intensity and inclination angle. [19659002] "It's an achievement in itself, but we already see opportunities for increasing the speed of up to a quadrillion hits per second! "said Jinyang Liang, an engineer at COIL when the research was conducted.
