Femto Photography: Capturing Pulses of Light

Check out this great TED Talk: Ramesh Raskar – Imaging at a trillion frames per second http://on.ted.com/h42N

Ramesh uses a new technique called femto-photography that is so fast is captures beams of light traveling in mid-air; aggregating the photographs into videos show how a beam of light travels through an object, reflects, refracts and bounces around.  Amazing!
