Abstract: The present application discloses examples of various apparatuses and systems that can be utilized for augmented reality. According to one example, a wearable device that can optionally comprise: a frame configured for wearing by a user; one or more optical elements mounted on the frame; an array having a plurality of light emitting diodes coupled to the one or more optical elements, wherein the one or more optical elements and the array are mounted within a field of view of the user when the frame is worn by the user; and additional onboard electronic components carried by the frame including at least a battery that is configured to provide for electrically powered operation of the array.

Abstract: A lightweight stacked optical waveguide using two plastic substrates having nano-structure gratings and a single glass substrate sandwiched between them. The nano-structure gratings face each other, and are each encapsulated within the optical waveguide. The two plastic substrates are each adhesively secured to the central glass substrate rather than to each other to provide sufficient securing strength and precisely establish and maintain an air gap between the substrates. The thickness of the plastic substrates and the glass substrate are selected such that the stacked optical waveguide is lightweight, but also has sufficient drop performance. The stacked optical waveguide can be efficiently manufactured as the adhesive bonds a plastic substrate to a glass substrate.

Abstract: A method for configuring a digital light projector (DLP) of an augmented reality (AR) display device is described. A light source component of the DLP projector is configured to generate a single red-green-blue color sequence repetition per image frame. The AR display device identifies a color sequence of the light source component of the DLP projector and tracks a motion of the AR display device. The AR display device adjusts an operation of the DLP projector based on the single red-green-blue color sequence repetition, the color sequence of the light source component of the DLP projector, and the motion of the AR display device.
