Interface device with three-dimensional (3-D) viewing functionality
An interface device is provided that is configured to allow viewing of three-dimensional (3-D) content when the interface device is worn. In certain embodiments, a wearable visualization device can be removably coupled to the interface device. The wearable visualization device, when in use, may provide additional viewing functionality, such as facilitating the viewing of augmented reality (AR) or virtual reality (VR).
HYPERCHROMATIC IMAGING SYSTEM WITH ANGULAR RESOLUTION
A hyperchromatic three-dimensional (3D) imaging system creates multiple planar (2D) images located at different planes which are perceived by the observer's eyes as a 3D image, whereas a new functionality is added. Brightness of the display images is increased by applying narrow diffusion angles for the light scattered by the display. Narrow diffusion angle of the light also allows displays generating images such that each 2D image depends on the angle of observation, and a plurality of 2D images is perceived by the observer's eyes as a 3D image dependent on the angle of observation in a certain interval of the angles of observation. Angular spatial light modulator is employed as a display to generate beams directed in several predefined directions, beams being separately encoded for each direction. Scanning of an angle-maintaining diffuser screen by laser impinging onto the diffuser at different angles can be applied to ensure angle-resolved multi-view functionality.
3D EYEWEAR ADAPTED FOR FACIAL GEOMETRY
Three dimensional (3D) glasses suited for wearers with varying facial geometries are disclosed. A particular embodiment includes a frame adapted to position spectrally filtering lenses at a particular distance from the eyes of the wearer. In a more particular embodiment, the 3D glasses include a means for adjusting the distance between the lenses and the eyes of the wearer. In another particular embodiment, the lenses include positive runout.

OPTICAL DESIGN AND OPTIMIZATION TECHNIQUES FOR 3D LIGHT FIELD DISPLAYS
Methods and frameworks for designing and optimizing of high-performance light field displays, such as integral imaging head-mounted displays, are disclosed. The disclosed techniques enable user-defined metrics for characterizing the performance and optimization of such systems. One design method relates to an integral-imaging based three-dimensional (3D) display system that includes an arrayed optics, an arrayed display device to produce a plurality of elemental images, a first reference plane representing a virtual central depth plane (CDP), a second reference plane representing a viewing window for viewing a reconstructed 3D scene, and an optical subsection representing a model of a human eye. The method includes tracing rays starting at the arrayed display device, through the arrayed optics, and to the optical subsection for each element of the arrayed display device and arrayed optics, and adjusting one or more parameters to obtain at least a first metric value within a predetermined value.

OPTICAL SWITCH FOR SINGLE AND MULTIPLE PROJECTORS
A projection system and method therefor comprises a first light source configured to emit a first-eye light, wherein the first-eye light includes a first set of wavelengths; a second light source configured to emit a second-eye light, wherein the second-eye light includes a second set of wavelengths; a first projector including first projection optics configured to receive a first input light; and an optical switch configured to be switched between an a first mode and a second mode, wherein the optical switch is configured to, in the first mode, combine the first-eye light and the second-eye light into a combined light and direct the combined light to the first projection optics as the first input light.
3D PROJECTION SYSTEM USING LASER LIGHT SOURCES
Laser or narrow band light sources (e.g., red, green, and blue) are utilized to form left (e.g., R1, G1, B1) and right (e.g., R2, G2, B2) images of a 3D projection. Off-axis viewing of the projections which has the potential to cause crosstalk and/or loss of energy/brightness in any channel or color, is eliminated (or reduced to only highly oblique viewing angles) via the combined use of any of guard bands between light bands of adjacent channels, curvature of viewing filters, and selection of passband wavelengths that maximize usability of the passband as it “shifts” due to varying or increasing angles of off-axis viewing. Implemented with any number of light sources, the light sources selected may also be converted to showing 2D images where the additional light sources are utilized to affect a desirable increase in color gamut.
