Embodiment Construction

[0037] Figure 1A An embodiment of a holographic display system is shown comprising a first display 1001 comprising a light field display configured to project light along a set of projection optical paths 1036 to form at least a first A holographic surface 1016 , said first holographic surface has a first projected depth profile relative to the display screen plane 1021 . In an embodiment, the first holographic surface 1016 may be any surface in a holographic scene such as a part of an object, a face, a background scene, and the like. In an embodiment, the projected depth profile of the holographic surface 1016 may comprise the perceivable depth to a viewer (not shown) looking at the first display 1001 along a normal axis (not shown) of the display 1001 . Figure 1A The holographic display system of further comprises a relay system 102A positioned to receive light from the light field display 1001 along a first set of projection optical paths 1036 and to relay the received lig...

Abstract

Disclosed are systems and methods for redirecting light corresponding to a light field or holographic object such that imagery generated by a light field or other display is perceived by a viewer without having to address the display itself.

Description

technical field [0001] The present disclosure generally relates to systems configured to generate light corresponding to 2D, 3D or holographic images and further configured to relay the generated holographic images to a desired location. Background technique [0002] Many of the technologies that exist today are often unfortunately confused with holograms, including lenticular printing, Pepper's Ghost, glasses-free stereoscopic displays, horizontal parallax displays, head-mounted VR and AR displays (HMDs), and other such hallucinations under the general term "fauxlography". These technologies may exhibit some of the desirable properties of a true holographic display, yet lack the ability to stimulate human visual sensory responses in any sufficient manner. [0003] Light fields and holographic displays are the result of multiple projections, where energy surface positioning provides angular, color and brightness information propagated within the viewing volume. Unlike ster...
