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

Brian Haidet, a scientist creating videos on YouTube under the handle AlphaPhoenix, showed off a camera in a new video that can capture footage of a laser pointer at the speed of light. The camera is an update on a previous design that could capture footage at one billion frames per second, but it comes with a major caveat: it can only shoot one pixel at a time.Haidet's camera is made from a gimbal-mounted mirror, two tubes, a simple lens, a light sensor and some Python code to tie it all together. Pointed at a laser pointer, the camera's able to capture a beam of light at two billion frames per second, showing it smoothly traveling between mirrors, with speeds that vary depending on where the camera is in relation to the laser pointer. "Light moves about six inches, or 15 c [...]
