Someone made a 'camera' that can shoot at two billion frames per second

A scientist named Brian Haidet has developed a camera that can capture footage at a staggering two billion frames per second. This is an update to his previous design that could shoot at one billion frames per second. The camera uses a unique setup, including a gimbal-mounted mirror, tubes, a lens, and a light sensor, along with Python code to capture the footage. The camera can record a laser pointer's beam of light as it travels at the speed of light, showing it moving between mirrors at a speed of about 15 centimeters per frame. However, the camera can only capture one pixel at a time, so the footage is stitched together to create the final video. Haidet explains that creating a traditional camera capable of two billion frames per second would be prohibitively expensive and wouldn't provide significantly better results than his unique approach. While not a true two billion frames-per-second camera, Haidet's innovation is a remarkable achievement in high-speed videography.
