Streak cameras are used by chemists to capture light passing through samples and determine chemical properties. At the MIT Media Lab in Cambridge, Massachusetts, scientists have found a way to modify these streak cameras to capture motion – recording ultrashort pulses of light at up to a trillion frames per second. Project Director Dr. Ramesh Raskar calls this new technique “femto-photography.”
As described in the project abstract:
The eyes are the windows to the soul, or so goes the proverb. As humans, we use our eyes to express a wide variety of emotions, often without even realizing we’re doing so. Animators spend years studying eye movements to help them create characters with a range of believable expressions, but the eyes of robots and interactive toys are far more difficult to manipulate than those of cartoon characters.
