Abstract
An angular image of a scene may be displayed using a light field display. The light field display may comprise a plurality of projection units. Each of the projections units may comprise an imaging system and an optical system. The imaging system may illuminate pixels of a planar image of the scene. Light corresponding to each of the pixels may be directed towards the optical system. The optical system may comprise first and second lenses for redirecting each light beam corresponding to a pixel in different directions. In some embodiments the first and second lenses form a globe lens. A diffusion system may conceal the optical systems. Additionally, or alternatively, the diffusion system may produce a uniform distribution of light at a plurality of different viewing angles.
