- Our modification is to insert a patterned occluder within the aperture of the camera lens, creating a coded aperture. We introduce a criterion for depth discriminability which we use to design the preferred aperture pattern. Using a statistical model of images, we can recover both depth information and an all-focus image from single photographs ...

- Coded Aperture Projection. Figure 1: Two prototypes: a static attenuation mask integrated into the aperture plane of a projector improves digital defocus compensation through inverse filtering (left). Replacing the aperture with a transparent liquid crystal array allows dynamic attenuation mask patterns to be encoded (right).

- coded aperture photography, in that the traditional box-shaped exposure window is replaced with a coded pattern in order to engineer the PSF of moving objects. Coded exposures can be captured using a standard camera with an additional high-speed electronic shutter, and this has been shown to be useful
