Brian Haidet, a scientist creating movies on YouTube beneath the deal with AlphaPhoenix, confirmed off a digital camera in a brand new video that can seize footage of a laser pointer on the pace of sunshine. The digital camera is an replace on a earlier design that might seize footage at one billion frames per second, but it surely comes with a significant caveat: it may solely shoot one pixel at a time.
Haidet’s digital camera is constructed from a gimbal-mounted mirror, two tubes, a easy lens, a lightweight sensor and a few Python code to tie all of it collectively. Pointed at a laser pointer, the digital camera’s in a position to seize a beam of sunshine at two billion frames per second, displaying it easily touring between mirrors, with speeds that modify relying on the place the digital camera is in relation to the laser pointer. “Mild strikes about six inches, or 15 centimeters, per body of this video,” Haidet says. “This beam of sunshine is touring on the Universe’s pace restrict. Mild in any reference body won’t ever transfer any sooner or any slower than this pace.”
Pixels needed to be tiled collectively to create what seems to be like regular video footage.

Whereas it is theoretically attainable to create a extra conventional digital camera that may seize footage at two billion frames per second, as Haidet explains, you possibly can’t do it with the instruments most individuals have of their storage. His answer was to seize one pixel at a time, after which tile that footage collectively to create one thing viewable. Based on Haidet, “if all these movies are synchronized and we take many, many, many, one pixel movies, we will tile these movies subsequent to one another and play all of them again at the very same second and provides one thing that appears like a video.”
Whereas it isn’t the identical factor as a real two billion frames-per-second digital camera, “that is only a considerably dearer approach to do it,” Haidet says, “and it actually would not get us any higher of a end result.”
