World's fastest camera view the light in slow motion

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