    摘要: A display engine includes light emitting elements, an optical subsystem to produce a single collimated beam of light from the light emitted by the light emitting elements, one or more image producing MEMS mirrors, one or more image reprojecting MEMS mirrors, and a controller. One of the image producing MEMS mirror(s) is positioned to reflect the single beam of light produced by the optical subsystem. The controller controls the image producing MEMS mirror(s) and the image reprojecting MEMS mirror(s). The image reprojecting MEMS mirror(s) is/are controlled and is/are positioned relative to the image producing MEMS mirror(s) and relative to input-coupler(s) of optical waveguide(s) so that a pupil corresponding to a scanned image that the image producing MEMS mirror(s) project onto one of the image reprojecting MEMS mirror(s), is reprojected by the image reprojecting MEMS mirror(s) onto the input-coupler(s) of the optical waveguide(s) and thereby coupled into the optical waveguide(s).

    摘要: Examples are disclosed that relate to scanning optical systems. One example provides an optical system comprising an illumination source configured to emit light, a first scanning stage configured to receive the light and to scan the light, and a second scanning stage configured to receive and direct the light from the first scanning stage toward a projected exit pupil.

    摘要: One embodiment provides a computing device comprising a computing device body, a display coupled with the computing device body, a first set of computing components incorporated into the computing device body, and a securing system configured to secure the body to a wrist, the securing system comprising a plurality of detachable modular segments joined together to form a second set of computing components that is modifiable by changing segments. Each modular segment comprises a first mechanical connector and a second mechanical connector, a first set of electrical connectors and a second set of electrical connectors, and one or more electrical components incorporated into the modular segment, such that a functionality of the computing device is modifiable by changing modular segments.

    摘要: A near-eye display system comprises first and second optical waveguides. The first optical waveguide is configured to receive a first image through a first entry aperture, to expand the first image along the first optical waveguide, and to release an expanded first image. Layered parallel to the first optical waveguide, the second optical waveguide is configured to receive a second image through a second entry aperture, to expand the second image along the second optical waveguide, and to release an expanded second image to overlap the expanded first image. The second entry aperture is offset from the first entry aperture along the second optical waveguide.

    摘要: Examples are disclosed that relate to obtaining high-resolution images of regions of interest in a physical space. One disclosed example provides an imaging system, comprising a first camera, a second line-scan camera configured to capture a higher-resolution image than the first camera, a logic subsystem, and a storage subsystem. The storage subsystem holds instructions executable by the logic subsystem to, obtain, via the first camera, a lower-resolution image of a physical space, identify one or more regions of interest in the physical space based on the lower-resolution image, and, for each of the one or more regions of interest, obtain, via the second line-scan camera, a higher-resolution image of at least a portion of the region of interest.
