    Abstract: In embodiments of a multiple waveguide imaging structure, a wearable display device includes left and right imaging units of respective display lens systems to generate an augmented reality image that includes a virtual image. Each of the left and right imaging units include a first waveguide for see-through viewing at a first field of view, where the first waveguide includes a first polarizing beam splitter to reflect light that enters at a first polarization orientation angle and pass through the light that enters at a second polarization orientation angle. Each of the left and right imaging units also include at least a second waveguide for see-through viewing at a second field of view, where the second waveguide includes a second polarizing beam splitter to reflect the light that enters at the first polarization orientation angle and pass through the light that enters at the second polarization orientation angle.

    Abstract: An optical device comprises a pixel array including one or more pixels. Two or more independently controllable electrodes are electrically coupled to each pixel. A common ground reference electrode is electrically coupled to all pixels of the pixel array. Each pixel includes a plurality of liquid crystal molecules. The liquid crystal molecules may be oriented in a first direction based on a first function of voltages applied by the two or more independently controllable electrodes for the pixel, and oriented in a second direction based on a second function of the voltages applied by the two or more independently controllable electrodes for the pixel. In this way, both phase modulation and polarization modulation may be introduced to light illuminating the pixel array.

    Abstract: A non-telecentric display system that prevents ghost images includes an optical waveguide and a display engine. An image former of the display engine includes a reflective surface having a surface normal thereto. An illumination engine of the display engine emits light towards the reflective surface of the image former such that chief rays are offset by acute angles from the surface normal to the reflective surface. The display engine directs light corresponding to an image, that reflects off the reflective surface of the image former, towards an input-coupler of the optical waveguide so light corresponding to the image is coupled therein and travels by total internal reflection to an output-coupler of the waveguide. Ghost images are prevented at least in part due to the chief rays of light emitted by the illumination engine being offset by acute angles from the surface normal to the reflective surface.

    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.
