Three-dimensional display apparatus and methods are disclosed. The apparatus and methods generate three-dimensional images for an observer by providing components of the image in a series of frames to an image space. Providing the image components can include: scanning an image of a light shaping element over an image space wherein each of a plurality of zones of the light shaping element is projected to each of a plurality of zones of the image space; and, selectively illuminating portions of the light shaping element zones during each of several frames during the scan, wherein each light-shaping element zone scatters the illumination and at least a portion of the scattered illumination provides a component of the three-dimensional image in the image space.

Three-dimensional display systems

The invention provides systems and methods for generating and displaying computational holographic stereograms having a hologram surface and a spatially distinct image surface. A three-dimensional object or scene is captured or synthesized as a stack of views. The holographic stereogram is computed by obtaining a diffractive fringe vector e and a pixel slice v through the stack of views, and generating the holopixel representation f=ev. The holographic stereogram is displayed using one or more image surfaces that are spatially distinct from the hologram surface. the surfaces can be any two-dimensional structures defined on a three-dimensional space, including, but not limited to planar, cylindrical, spherical, or other surfaces. The holographic stereograms are adjustable through variations in an image surface depth, an image surface resolution, a number of image surfaces, and a scene parallax resolution.
