Abstract: A partially reflective thin film coating is utilized on an optical substrate that is affixed to a waveguide-based optical combiner in a see-through display of a mixed-reality head-mounted display (HMD) device to partially reflect a forward propagating holographic image light back to the user's eye. The thin film coating may be implemented as a broadband reflector over the angular range associated with the holographic images that are rendered over the field of view (FOV) of the virtual portion of the see-through display to simplify manufacturing and reduce bulk and weight of the HMD device.

Abstract: An optical system that deploys micro electro mechanical system (MEMS) scanners to contemporaneously generate CG images and to scan a terrain of a real-world environment. An illumination engine emits a first spectral bandwidth and a second spectral bandwidth into an optical assembly along a common optical path. The optical assembly then separates the spectral bandwidth by directing the first spectral bandwidth onto an image-generation optical path and the second spectral bandwidth onto a terrain-mapping optical path. The optical system deploys the MEMS scanners to generate CG images by directing the first spectral bandwidth within the image-generation optical path and also to irradiate a terrain by directing the second spectral bandwidth within the terrain-mapping optical path. Accordingly, the disclosed system provides substantial reductions in both weight and cost for systems such as, for example, augmented reality and virtual reality systems.

Abstract: MicroLED arrays offer a small form factor solution for the HMD image sources since they do not need a separate illumination optics. Features of the present disclosure implement a MicroLED display system that incorporate a plurality of monochrome projectors (e.g., three MicroLED projectors) to generate three monochrome images (e.g., red, blue, and green images) that are separately input into a single waveguide of the HMD and combined to form an image that is displayed to the user. By utilizing a single waveguide that includes a plurality of spatially separated input regions (e.g., a region for inputting blue light, a region for inputting red light, a region for inputting green light), the MicroLED display system of the present disclosure may reduce the form factor of the HMD device because of the reduced number of plates that may be required to combine the three monochrome images.

Abstract: Disclosed optical mounts are resistant to the various stresses that may be experienced by optical display devices. An optical mount is provided with mechanical compliance and resiliency. Such mechanical compliance and resiliency associated with the disclosed optical mounts are intended to absorb thermal and/or mechanical stresses, while protecting and preserving the operational functionality of optical waveguides coupled to the disclosed optical mounts.

Abstract: A near-eye-display device includes a pair of fluid-filled lenses. The power of an inner lens of the pair of lenses can be set to position a focal plane for a virtual object from infinity to a predefined distance. The optical power of an outer lens of the pair of lenses is set to cancel out the optical power of the inner lens. A single actuator coupled to a reservoir pumps fluid into or out of the lenses to change their optical power. When the actuator is activated, fluid flows into one of the lenses in a pair and out of the other lens in the pair. The amount of fluid in each lens in a pair of lenses is thereby maintained to cancel out the optical power of the other lens. A single actuator can also be utilized to modify the power of two or more pairs of lenses.

Abstract: Near-to-eye devices with steerable phased arrays are provided. In some configurations, a device comprises waveguides, e.g., color plates, that are individually formed to couple a corresponding color output of a micro-display engine and project an image into a human vision system. Some configurations include steerable phased arrays for generating light defining a field of view of image content. The generated light is aligned with light from a real-world view to create an output that concurrently displays the real-world view with the field of view of the image content. The light from the steerable phased arrays is directed through one or more waveguides to an output region of the one or more waveguides. The light from the real-world view can pass through transparent portions of waveguides in a manner that aligns a rendering of the image content with the light from the real-world view to create augmented reality views.
