摘要:
A holographic display system for generating a super hologram with full parallax in different fields of view in the horizontal and vertical directions. The display system includes assemblies or subsystems each adapted to combine holographic displays and coarse integral displays to produce or display a coarse integral hologram. The display system is adapted to combine such displays or display systems to add more detail or information. For example, the display system can be assembled as if it were made up of “holographic bricks” that can be stacked and combined to provide a unique image/output. Briefly, the display system described herein teaches techniques for combining coarse integral holographic (CIH) displays in a seamless and scalable manner, e.g., a display system where multiple spatial light modulators (SLMs) can be placed or provided behind coarse integral optics.
摘要:
A display assembly for displaying a virtual image of an object with occlusion and contrast. The display assembly includes a virtual object display selectively displaying an image at a virtual object plane. The display assembly includes a mask generation screen assembly with a screen element operable in a first state in which the screen element is transparent to visible light and in a second state in which a portion is opaque. The screen element is positioned proximate to the virtual object plane. The opaque portion of the screen element corresponds in size, shape, and location to the displayed virtual object image to provide a mask for the virtual image. The screen element may include a projectable mask screen opaque in regions exposed to a predefined type of non-visible light. The non-visible light may be ultraviolet (UV) light or infrared (IR) light selectively provided by a UV or IR projector.
摘要:
A dual layer display system for generating dimensional imagery. The system includes a first display device and a second display device with a light source. The second display device is arranged to be spaced apart from the first display device and to project output light onto a back surface of the first display device. The system alternatively operates the display devices in a first mode in which the first display device is transparent and the second display device displays back layer content and in a second mode in which the first display device displays front layer content and the second display device operates as a backlight to the first display device. In the first mode, the first display device displays a mask for the front layer content such as with gray-to-black pixels mapped to an object in the front layer content to block back layer content at this location.
