The rapid-fire camera in the world can do 10 trillion fps
Slow motion videos are always interesting to watch, and the best camera for this kind of task usually are able to shoot a few thousand frames per second. But now the camera developed by researchers from Caltech and INRS, leaves the best solutions far behind, being able to take pictures with a staggering 10 trillion frames per second is fast enough to explore the interactions between light and matter at the nanoscale.
Last year, the record belonged to Swedish team that made the creation of the camera with the figure of 5 trillion fps, improving an earlier decision is capable of doing 4.4 trillion fps New camera doubles the previous record, which can facilitate analysis of what is happening in the nanoworld with a higher “temporal” resolution.
In the new method of shooting the team started with compressed ultrafast photography (CUP) method, which is able to capture at a frequency of 100 billion fps Is impressive, but not enough to effectively record what is happening with ultrafast laser pulses in the femtoseconds scale. Femtosecond — is one kvadrilliona a fraction of a second.
Therefore, a team of scientists have combined the technology CUP with a static camera and the technology of data collection, known as the Radon transform — an improved system was named T-CUP.
“We knew that using a single femtosecond camera, the image quality is limited, — said one of the lead authors of the study Lihong Wang (Wang Lihong). — To improve this figure, we added another camera, which records a static image. In conjunction with the image obtained with the femtosecond camera, we can use the so-called Radon transform to get high-quality images while recording ten trillion frames per second”.
