摘要： A stacked waveguide assembly can have multiple waveguide stacks. Each waveguide stack can include a plurality of waveguides, where a first waveguide stack may be associated with a first subcolor of each of three different colors, and a second waveguide stack may be associated with a second subcolor of each of the three different colors. For example, the first stack of waveguides can incouple blue, green, and red light at 440 nm, 520 nm, and 650 nm, respectively. The second stack of waveguides can incouple blue, green, and red light at 450 nm, 530 nm, and 660 nm, respectively.

摘要： A display subsystem for a virtual image generation system. The display subsystem comprises a planar waveguide apparatus, and an optical fiber having a distal tip affixed relative to the planar waveguide apparatus, and an aperture proximal to the distal tip. The display subsystem further comprises at least one light source coupled the optical fiber and configured for emitting light from the aperture of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the aperture of the optical fiber in accordance with a scan pattern. The display subsystem further comprises an optical waveguide input apparatus configured for directing the light from the aperture of the optical fiber down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to the end user.

摘要： Examples of a light field metrology system for use with a display are disclosed. The light field metrology may capture images of a projected light field, and determine focus depths (or lateral focus positions) for various regions of the light field using the captured images. The determined focus depths (or lateral positions) may then be compared with intended focus depths (or lateral positions), to quantify the imperfections of the display. Based on the measured imperfections, an appropriate error correction may be performed on the light field to correct for the measured imperfections. The display can be an optical display element in a head mounted display, for example, an optical display element capable of generating multiple depth planes or a light field display.

摘要： A virtual image generation system for use by an end user comprises a projection subsystem configured for generating a collimated light beam, and a display configured emitting light rays in response to the collimated light beam to display a pixel of an image frame to the end user. The pixel has a location encoded with angles of the emitted light rays. The virtual image generation system further comprises a sensing assembly configured for sensing at least one parameter indicative of at least one of the emitted light ray angles, and a control subsystem configured for generating image data defining a location of the pixel, and controlling an angle of the light beam relative to the display based on the defined location of the pixel and the sensed parameter(s).
