Þarna hefur vísindamönnum tekist að ná myndbandi af því þegar ljósgeisli ferðast í gegnum kókflösku. Þetta samsvarar til 1.000.000.000.000 frames/second. Í raun eru þetta margar ljósmyndir sem búið er að splæsa saman í video. Gildir einu. Þetta er kyngimagnað.
Í videoinu er líka sýnt hvernig tæknin er notuð til að sjá fyrir horn með því að nota endurkast ljóseindanna. Myndbandið segir alla söguna. Mæli með því.

Why you should listen to Ramesh Raskar:
In 1964 MIT professor Harold Edgerton, pioneer of stop-action photography, famously took a photo of a bullet piercing an apple using exposures as short as a few nanoseconds. Inspired by his work, Ramesh Raskar and his team set out to create a camera that could capture not just a bullet (traveling at 850 meters per second) but light itself (nearly 300 million meters per second).
Stop a moment to take that in: photographing light as it moves. For that, they built a camera and software that can visualize pictures as if they are recorded at 1 trillion frames per second. The same photon-imaging technology can also be used to create a camera that can peer "around" corners , by exploiting specific properties of the photons when they bounce off surfaces and objects.
Among the other projects that Raskar is leading, with the MIT Media Lab's Camera Culture research group, are low-cost eye care devices, a next generation CAT-Scan machine and human-computer interaction systems. "Though photographs in the near future will still be composed by people holding cameras, it will gradually become more accurate to say pictures were computed rather than 'taken' or 'captured.'"
