Science Daily  January 13, 2021 Chaotic systems play a large role in the world around us. They exhibit behavior that is predictable at first but grows increasingly random with time. A team of researchers in the US (Caltech, University of Southern California) designed an ultrafast camera that recorded video at one billion frames per second to observe the movement of laser light in a chamber specially designed to induce chaotic reflections where light takes a different path every time the experiment is repeated. Compressed ultrafast photography (CUP) cameras are capable of speeds as fast as 70 trillion frames per second […]

Phys.org  January 20, 2020 Researchers at Caltech have developed a new imaging system, phase-sensitive compressed ultrafast photography (pCUP), that combines with phase-contrast microscopy, that was designed to allow better imaging of objects that are mostly transparent such as cells. They adapted the standard phase-contrast microscopy so that it provides very fast imaging. The system consists of lossless encoding compressed ultrafast technology (LLE-CUP) which takes a single shot, capturing all the motion that occurs during the time that shot takes to complete. LLE-CUP is capable of capturing motion, such as the movement of light itself. They demonstrated the capabilities of pCUP […]
