Light Field Camera- An article from "Science Daily"

Ren Ng, a computer science graduate student in the lab of Pat Hanrahan, the Canon USA Professor in the School of Engineering, has developed a "light field camera" capable of producing photographs in which subjects at every depth appear in finely tuned focus. Adapted from a conventional camera, the light field camera overcomes low-light and high-speed conditions that plague photography and foreshadows potential improvements to current scientific microscopy, security surveillance and sports and commercial photography.

The light field camera adds an additional element—a microlens array—inserted between the main lens and the photosensor.Each lenslet separates back out the converged light rays received from the main lens before they hit the photosensor and changes the way the light information is digitally recorded
