A Research team at Caltech, California reached an astonishing development in the world of photography with their new project on Compressed Ultrafast Spectral Photography which can provide an output of 70 trillion Frames per second. Technically speaking this CUSP is a real-time multidimensional imaging technology that can find its applications in numerous fields in scientific studies like capturing rapid events or for detailed spectral information without the need of repetitive experiments.
According to the report by the authors, this system consists of two Modes.
In active mode, it can take pictures quickly up to 70 trillion frames per second(fps) and capture 1000 of these frames at the same time with the help of the most advanced techniques like spectral encoding, pulse splitting, temporal shearing, and compressed sensing. Below is the gif which shows the difference between Compressed Ultrafast Photography (CUP) and its successor Compressed Ultrafast Spectral Photography (CUSP) imaging an ultrafast linear optical phenomenon.
So then, In Passive Mode- CUSP works at the slow speed of 0.5 trillion Frames Per Second with an ability of Four-Dimensional (4D) Spectral Imaging. This means it can capture detailed information about how things glow in different colors and how long that glow lasts.
