Abstract
A light field projector device is described which outputs a light field. The projector has a projector base with a projection optical system configured to output light rays to form a projected image, a collimating optical system configured for collimation of the projected image light rays to form a second projected image, which is directed to a display optical system to produce a light field image. Light field projector devices may be used individually or in combination with one or more other projectors which can be arranged to form a direct projection light field display. The arrangement of light field projector devices may have an individual or shared display optical system. The projector device is designed to provide high pixel density, providing an image that looks crisp and unpixellated.
