Libai Huang makes "movies" of the interaction between light and matter (VIDEO)
Caption
Libai Huang describes her microscopy technique as similar in many ways to a digital camera, in that it has lenses and light detectors. But in place of a shutter, she uses a pulsed laser that can fire as fast as once per femtosecond. Just as a sports photographer would use a fast shutter speed to capture a clear image of an athlete in motion, the pulsed laser is an ultrafast shutter that provides just enough light to capture clear images of energy-carrying particles moving through materials.
