摘要： Technology is described for a projection optical system which optically couples image light from an image source to a near-eye display (NED) of a wearable near-eye display device. The projection optical system and the image source make up a projection light engine. Light from the image source is directed to a birdbath reflective optical element which is immersed in high index glass. The image light is reflected and collimated by the birdbath element and travels outside a housing of the projection light engine forming an external exit pupil, meaning the exit pupil is external to the projection light engine. A waveguide optically couples the image light of the external exit pupil. An example of a waveguide which can be used is a surface relief grating waveguide.

摘要： A scroll wheel assembly for computer input device having a housing. The scroll wheel assembly includes a housing and an engagable scroll wheel. The scroll wheel is rotatable with a shaft to preferably cause vertical scrolling of an image on a display. The scroll wheel is laterally tiltable relative to the housing and the shaft. A sensor is preferably positioned within the housing for sensing tilting of the rotatable member. In response to sensed tilting movement of the rotatable member, the image is horizontally scrolled, preferably in the direction of the lateral movement. The computer input device having the rotatable member may take the form of a keyboard, a mouse, a trackball device, or another type of computer input device.

摘要： 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.

摘要： In embodiments of reflective array waveguide, a reflective array waveguide includes clear waveguide panels for see-through viewing of an environment viewed through the reflective array waveguide. The reflective array waveguide also includes reflecting waveguide panels to reflect a virtual image that is generated to appear as part of the environment. Each of the reflecting waveguide panels have a partially reflective mirror coating deposited on opposing sides, and the reflecting waveguide panels are alternated in the reflective array waveguide with the clear waveguide panels. The alternating clear and reflecting waveguide panels are angled for augmented reality imaging of the reflected virtual image as part of the environment that is viewed through the reflective array waveguide.

摘要： A light guide includes at least two channels from which light is shined on a target area. The multiple channels disperse light across the target area more uniformly and with fewer dead or bright spots. The channels may be integral to one another, and may be molded. The light guide may further include an integral holder for supporting and aligning a LED light source to shine upon an entrance surface of the light guide. The entrance surface may also be formed as a collection lens. The channels may also be configured to direct light onto a target area at different angles. One or more of the channel faces from which light emanates may also be non-planar.

摘要： An optical system for forming an image of at least a portion of an illuminated area on an object may comprise a lens positioned a spaced distance from the illuminated area on the object and an aperture stop positioned so that it is substantially co-planar with the image side focal plane of the lens. An occluding element is positioned between the lens and the illuminated area on the object so that the occluding element blocks a predetermined amount of light from a brightly illuminated region in the illuminated area but does not substantially block light from a less brightly illuminated region in the illuminated area.
