Paper Abstract

The paradigm theorem of light field optics is different from that of conventional imaging optics. The conditions for rays in a 3D space are reconstructed from the light field data shown on a 2D high definition flat display through the lens array. A light field display consists of a flat display and lens array attached on its screen. The light field display can be regarded as a transformation system for the light field data. Further, the light field data can be considered as 3D space information in another domain. It contains information of rays in a space, and a point light source in space is expressed as information of many rays that go through the point light source. A point light source in space represents a set of many point light sources, and each ray that composes a point light source should be described in the light field data. Therefore, the light field flat display requires a much higher resolution as compared to that required by a conventional imaging device, on which a point light source can be expressed by a single pixel. In this study, we developed various light field displays using high definition flat displays, introduced the theorem of light field display, and reported the examples of our experimental light field displays.
