Results of refocusing with relative rotation between two DOEs.

(a) A screw is located 10 mm in front of the lens and a poker card on a magic cube is located 1500 mm further away. (b) When the lens is focused on the rear poker card, the front screw is hardly seen due to the strong out of focus. (c) When the lens is focused on the screw, the poker card is severely blurred. (d) Captured image when the lens is focused on the rear beam-splitter cage. (e) Reconstructed image of (d). (f) Captured image when the lens is focused on the foreground doll. (g) Reconstructed image of (f). Insets of the results from (d,e) indicate that our algorithm is robust to both saturated and dark areas in the same scene. Subfigure (b,c) had to be cropped for copyright reasons. The focal length range of the encoded lens for experimental results shown here is .
