With this technology cameras can capture fstop as value of depth literaly. Basically with one sensor you can capture 3D.
"Our system can be used with commercially available DSLR cameras and photographic lenses without modification to either. We leverage the fact that defocus blur is a function of scene depth and f/# to estimate a depth map. We demonstrate several applications of our multi-aperture camera, such as post-exposure editing of the depth of field, including extrapolation beyond the physical limits of the lens, synthetic refocusing, and depth-guided deconvolution."
Interesting tech, the lens Is CRAZY!!!
