    Abstract: An optical system for an augmented reality head mounted display eyepiece that is configured to deliver images to the eye wherein the optical system includes optics. The optics are disposed so as to receive light output from the light source. The optics further arranged with respect to a spatial light modulator such that the light received from the light source passes through the optics and illuminates the spatial light modulator. The light illuminating the spatial light modulator is redirected back through the optics and is coupled into at least one waveguide through at least one in-coupling optical element. At least a portion of the coupled light is ejected from at least one waveguide by at least one out-coupling optical element and directed to the eye of the user.

    Abstract: Images perceived to be substantially full color or multi-colored may be formed using component color images that are distributed in unequal numbers across a plurality of depth planes. The distribution of component color images across the depth planes may vary based on color. In some embodiments, a display system includes a stack of waveguides that each output light of a particular color, with some colors having fewer numbers of associated waveguides than other colors. The stack of waveguides may include by multiple pluralities (e.g., first and second pluralities) of waveguides, each configured to produce an image by outputting light corresponding to a particular color. The total number of waveguides in the second plurality of waveguides is less than the total number of waveguides in the first plurality of waveguides, and may be more than the total number of waveguides in a third plurality of waveguides, in embodiments where three component colors are utilized.

    Abstract: An eyepiece for projecting an image to an eye of a viewer includes a first planar waveguide positioned in a first lateral plane, a second planar waveguide positioned in a second lateral plane adjacent the first lateral plane, and a third planar waveguide positioned in a third lateral plane adjacent the second lateral plane. The first waveguide includes a first diffractive optical element (DOE) coupled thereto and disposed at a lateral position. The second waveguide includes a second DOE coupled thereto and disposed at the lateral position. The third waveguide includes a third DOE coupled thereto and disposed at the lateral position. The eyepiece further includes a first optical filter disposed between the first waveguide and the second waveguide at the lateral position, and a second optical filter positioned between the second waveguide and the third waveguide at the lateral position.

    Abstract: Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a scanning device for scanning one or more frames of image data. The scanning device may be communicatively coupled to an image source to receive the image data. The system may further comprise a variable focus element (VFE) operatively coupled to the scanning device for focusing the one or more frames of image data on an intermediate image plane, wherein the intermediate image plane is aligned to one of a plurality of switchable screens. The plurality of switchable screens may spread light associated with the intermediate image plane to specific viewing distances. The system may also comprise viewing optics operatively coupled to the plurality of switchable screens to relay the one or more frames of image data.

    Abstract: An optical device comprising may include a light turning element. The optical device can include a first surface that is parallel to a horizontal axis and a second surface opposite to the first surface. The optical device may include a light module that includes a plurality of light emitters. The light module can be configured to combine light for the plurality of emitters. The optical device can further include a light input surface that is between the first and the second surfaces and is disposed with respect to the light module to receive light emitted from the plurality of emitters. The optical device may include an end reflector that is disposed on a side opposite the light input surface. The light coupled into the light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.

    Abstract: This disclosure describes a wearable display system configured to project light to the eye(s) of a user to display virtual (e.g., augmented reality) image content in a vision field of the user. The system can include light source(s) that output light, spatial light modulator(s) that modulate the light to provide the virtual image content, and an eyepiece configured to convey the modulated light toward the eye(s) of the user. The eyepiece can include waveguide(s) and a plurality of in-coupling optical elements arranged on or in the waveguide(s) to in-couple the modulated light received from the spatial light modulator(s) into the waveguide(s) to be guided toward the user's eye(s). The spatial light modulator(s) may be movable, and/or may include movable components, to direct different portions of the modulated light toward different ones of the in-coupling optical elements at different times.
