According to the latest issue of the journal Nature, this figure may be about 100 billion frames per second. Researchers from the University of Washington, Saint Louis, used a system called ultra-high-speed compression photography (CUP) to capture the propagation and reflection of light. The researchers captured the spread of light through professional striped cameras and sensors and recorded where they moved. The previous stripe camera was limited to capturing static images, and this time the researchers filmed the entire two-dimensional video. A laser pulse propagation and the process of specular reflection are shown in the video.
