1,000,000,000,000 Frames/Second Photography – Ramesh Raskar

[chrisnobbs-blog]

"Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look "around" corners or see inside the body without X-rays" @youtube

Visualizing video at the speed of light — one trillion frames per second

By now, most of you have probably seen mention of this video, where MIT scientists have created a camera that visualizes light at a trillion frames per second. In my moments of "wow face", I realized I was remiss in not offering up an explainer of this bad-ass technology.

The MIT group does a pretty good job of detailing what's going on in the video above, but if you need more:

The special camera in their setup is called a "streak camera". Picture a camera that takes an image on one "slit" plane at a time, sort of like a stack of lines eventually becoming a rectangle. Then, there are 500 individual sensors in the camera timed to go off a trillionth of a second apart., each sort of corresponding to what we would think of as a "frame" of a video.

In that video, every "frame" of the Coke bottle with light moving through it was one-trillionth of a second. They had to repeat the scan hundreds of times to assemble a full "rectangular" image like we are used to, changing the position of the slit in the camera over time.

The result is a series of images over time that show how actual light particles move through and over a solid object. It's slow, but the possibilities are many, from medical imaging to future YouTube video awesomeness.
