<p>An optical system that has two-dimensional, three-dimensional and inverse three-dimensional modes. A light valve using a plurality of regions of differing optical transmission. An optical system using a leading (103 and 105) and/or analyzing filter (104) that encodes only a portion of the light encoded by an encoder (101) positioned at the aperture stop or conjugate thereof. A digit iris (3601) which includes a plurality of independently controllable pixels. Each pixel can include an active optical material such as a liquid crystal material and electrical conductors to apply a voltage across the material. The pixel alternates between transmissive and occlusive states.</p> |
