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 waveguide optics focus elements, an imaging structure includes a waveguide for viewing of an environment that is viewable with the imaging structure. The waveguide transmits light of a virtual image that is generated to appear as part of the environment for augmented-reality imaging or virtual-reality imaging. The imaging structure also includes one or more focus elements that are integrated in the waveguide and switchable to focus the virtual image at a focus depth that approximately correlates to a focal distance of the environment. The focus elements can each be implemented for a different focus depth of the virtual image, and the focus depth is adjustable based on a combination of the focus elements being switched-on or switched-off.

Abstract: In embodiments of laser illumination scanning, an imaging unit includes a linear array of spatial light modulators that direct light in a direction perpendicular to an imaging scan direction. The lasers each emit the light through a diffractive optic that uniformly illuminates the spatial light modulators, and a scanning mirror then scans the spatial light modulators to generate a two-dimensional image for display. The lasers can include red, green, and blue lasers for RGB illumination of the spatial light modulators, which can be implemented as reflective liquid crystal on silicon (LCOS), transmissive LCOS, or as micro-electro-mechanical systems (MEMS) mirrors.

Abstract: In embodiments of eyebox adjustment for interpupillary distance, a first optical lens receives light of an image from a display optic at a projected orientation of the light, and the first optical lens deviates the light of the image by a deviation angle from the projected orientation of the light. A second optical lens receives the light of the image from the first optical lens at the deviation angle, and the second optical lens alters the deviated light of the image back to the projected orientation of the light for viewing the image. Left and right eyeboxes align with respective left and right eyes that view the image, and a distance between the left and right eyeboxes approximately correlates to an interpupillary distance between the left and right eyes. The light of the image can be laterally shifted to increase or decrease the distance between the left and right eyeboxes.

Abstract: In embodiments of a double hinge torsion bar, a portable device includes a first housing integrated with a display device, and a second housing movably coupled to the first housing. Double hinges attach to the first and second housings of the portable device, and the double hinges are operable to open and close the first and second housings relative to each other. A torsion bar movably couples the double hinges to open and close at approximately a same timing rate, which can prevent the double hinges from binding when the first and second housings are opened and closed relative to each other.

Abstract: Architecture for managing clutch height in an optical navigational device such as a computer mouse. In one embodiment for a mouse, a feature can be molded into the bottom case that limits the clutch height by occluding the reflected light to the image sensor when the device is lifted from the tracking surface. Tracking is disabled when the clutch height threshold is exceeded, and re-enabled when the device is brought under the distance clutch height threshold. The device includes firmware controlled algorithm adjustments to one or more correlation parameters. When employing a D-shaped aperture, a threshold can be placed on the z-axis height tracking distance using dimensional characteristics of the shaped aperture, such as a knife-edge (the straight portion of the “D” shaped aperture), to impose a shadow across the image sensor. The aperture can be custom designed to occlude a portion of the emitted light from an LED.
