摘要： A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparatus may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.

摘要： Disclosed is a system for scanning electromagnetic imaging radiation. The system alleviates at least some of the challenges associated with imaging systems such as head mounted displays. These challenges include the pixel density of image sources, which is constrained by the minimum achievable pixel size. The system comprises a drive electronics system configured to generate at least one pixel modulation signal, at least one electromagnetic radiation source configured to modulate light from the at least one electromagnetic radiation source based on the at least one pixel modulation signal, a first waveguide configured to follow a scan pattern and produce a first projected field area, a second waveguide configured to follow a scan pattern and produce a second projected field area, a first scanning actuator operatively coupled to and configured to physically displace the first waveguide, and a second scanning actuator operatively coupled to and configured to physically displace the second waveguide. Each of the first waveguide and the second waveguide is operatively coupled to the at least one electromagnetic radiation source. The drive electronics system is configured to luminance modulate the output of at least one of the first waveguide or the second waveguide concurrent with the first projected field area overlapping with the second projected field area.
