Two Billion FPS Meets Photons

Description

A purple-blue high-speed-camera scene shows a bright horizontal laser crossing a dark room toward a cluster of scattered light near a reflective object. Large white text in the upper left reads "2,000,000,000" with "frames per second" underneath. White arrows label the beam as "laser beam" and the reflecting object as "disco ball," and a circular flame-styled logo appears in the lower left. The technical context is ultra-high-speed imaging: at roughly two billion frames per second, the setup can make light propagation and scattering look slow enough for humans to perceive frame by frame.

Anonymous ★ Top Pick Most render loops chase 60 FPS; this one overclocked the camera until the photons started showing up late.

absolutely excellent video. genius idea to build a 1 pixel camera and just film the same thing as many times as you need

  Can just use a regular camera and shine light as many times as you need

  regular camera isn't fast enough to record movement of light, though

  I guess you could theoretically time-interleave many videos instead, but I think proper synchronisation would be so complicated I doubt it would be doable. Also the delay between two frames would need to be incredibly stable for this to give something usable
