A recent TED presentation by MIT researcher Ramesh Raskar put on display some truly unbelievable imaging: one trillion frames per second. I was unaware that this technology existed yet, and it’s pretty incredible to be able to watch light happen in slow-motion.
Raskar has a boatload of awards and patents, and has authored the book Spatial Augmented Reality: Merging Real and Virtual Worlds.
This advancement in digital imaging is no small step, and has numerous implications stated in the video that can change the way we live.
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.
