Description: 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.

Imaging at a trillion frames per second

A revolutionary imaging technique, femto-photography, can record the movement of light itself at one trillion frames per second. This technology lets researchers create slow-motion videos of photons bouncing, scattering, and revealing hidden details. One experiment shows light rippling through a bottle in less than a nanosecond, slowed down by a factor of ten billion. Such cameras could someday see around corners or detect ripe fruit without touching it.
