Abstract: A system and method are disclosed for providing uniform color distribution of light emitted from a light source to an eye box in a near eye display (NED). An example of the system and method uses an optical element including two or more waveguides optimized to different colors of the visible light spectrum. The optical element further includes one or more polarization state generators for controlling the polarization of light incident on the waveguides to facilitate coupling of light into a matched waveguide, and to impede coupling of light into unmatched waveguides.

Abstract: In embodiments of wearable display device calibration, a first display lens system forms an image of an environment viewed through the first display lens system. A second display lens system also forms the image of the environment viewed through the second display lens system. The first display lens system emits a first reference beam and the second display lens system emits a second reference beam. The first display lens system then captures a reflection image of the first and second reference beams. The second display lens system also captures a reflection image of the first and second reference beams. An imaging application is implemented to compare the reflection images to determine a misalignment between the first and second display lens systems, and then apply an alignment adjustment to align the image of the environment formed by each of the first and second display lens systems.

Abstract: A near-eye display system includes an image former and first and second series of mutually parallel beamsplitters. The image former is configured to form a display image and to release the display image through an exit pupil. The first series of mutually parallel beamsplitters is arranged to receive the display image from the image former. The second series of mutually parallel beamsplitters is arranged to receive the display image from the first series of beamsplitters, and to release the display image through an exit pupil longer and wider than that of the image former. The second series of beamsplitters has a different alignment and a different orientation than the first series of beamsplitters.

Abstract: A near-eye display system includes an image former and a waveguide. The image former is configured to form a display image and to release the display image through a first exit pupil. The waveguide presents a back surface that faces the wearer's eye, and a front surface opposite the back surface. The waveguide is substantially transparent to external imagery received normal to the front surface, and is configured to receive the display image from the image former and to release the display image through a second exit pupil, which is larger than the first exit pupil.

Abstract: In embodiments of double hinge radial cams, a portable device includes a first housing integrated with a display device, and a second housing movably coupled to the first housing. The first housing is operable to open and close relative to the second housing, and the first and second housings can be rotated from a closed position at approximately zero degrees (0°) to an open position at approximately one-hundred and eighty degrees (180°). A double hinge is operable to movably couple the first housing and the second housing. The double hinge includes radial cams that apply a holding torque in the open position that resists the first and second housings closing.
