Abstract
A display system for presenting a holographic image to a viewer may comprise a coherent light source, a display element, and a computing device operatively connected to the coherent light source and the display element, the coherent light source emitting a light that enters the display element from the same side of the viewer, and the display element comprising a liquid crystal layer and a partially-transmissive-partially-reflective layer, wherein the computing device is configured to provide a control signal to the display element to present the holographic image, wherein the liquid crystal layer receives light from the light source and is controlled by the control signal to modulate a phase of the light from the light source, and wherein the partially-transmissive-partially-reflective layer receives light from the liquid crystal layer and reflects the light back through the liquid crystal layer to the viewer.
