MIT Camera Capable of 1.71ps Exposure

The device has been developed by the MIT Media Lab’s Camera Culture group in collaboration with Bawendi Lab in the Department of Chemistry at MIT. A laser pulse that lasts less than one trillionth of a second is used as a flash and the light returning from the scene is collected by a camera at a rate equivalent to roughly half a trillion frames per second. However, due to very short exposure times (roughly two trillionth of a second) and a narrow field of view of the camera, the video is captured over several minutes by repeated and periodic sampling. The new technique is able to compose a single 2D movie of roughly 480 frames each with an effective exposure time of 1.71 picoseconds.

MIT's Youtube video shows the camera in work:

Thanks to RC and CDM for sending me the link!


  1. Actually every 3D time-of-flight camera is doing the same job in principle.

  2. It's amazing that the guy talks about a new photography by using this technique. His language is so commercial and I guess he will raise some money and set up a company....
