    Abstract: A head mounted display system configured to project a first image to an eye of a user, the head mounted display system includes at least one waveguide comprising a first major surface, a second major surface opposite the first major surface, and a first edge and a second edge between the first major surface and second major surface. The at least one waveguide also includes a first reflector disposed between the first major surface and the second major surface. The head mounted display system also includes at least one light source disposed closer to the first major surface than the second major surface and a spatial light modulator configured to form a second image and disposed closer to the first major surface than the second major surface, wherein the first reflector is configured to reflect light toward the spatial light modulator.

    Abstract: An apparatus including a set of three illumination sources disposed in a first plane. Each of the set of three illumination sources is disposed at a position in the first plane offset from others of the set of three illumination sources by 120 degrees measured in polar coordinates. The apparatus also includes a set of three waveguide layers disposed adjacent the set of three illumination sources. Each of the set of three waveguide layers includes an incoupling diffractive element disposed at a lateral position offset by 180 degrees from a corresponding illumination source of the set of three illumination sources.

    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: 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.
