A multiplexed light field projector device and a multiplexed light field display to output a light field image is described. 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 or alternative projector devices may be used individually or in combination with one or more other projectors which can be arranged to form a multiplexed direct projection light field display. The arrangement of projector devices may have an individual or shared display optical system.

A beam splitterreflects a portion of light emitted from a first image projector in a first direction while allowing another portion of the light to transmit in a second direction. A first retroreflectorretroreflects the light reflected in the first direction toward the beam splitter. A second retroreflectorretroreflects the light transmitted in the second direction toward the beam splitter. The beam splitterallows the light retroreflected by the first retroreflectorto transmit toward an imaging opticswhile reflecting the light retroreflected by the second retroreflectortoward the imaging optics.
