Abstract: Illuminations systems that separate different colors into laterally displaced beams may be used to direct different color image content into an eyepiece for displaying images in the eye. Such an eyepiece may be used, for example, for an augmented reality head mounted display. Illumination systems may be provided that utilize one or more waveguides to direct light from a light source towards a spatial light modulator. Light from the spatial light modulator may be directed towards an eyepiece. Some aspects of the invention provide for light of different colors to be outcoupled at different angles from the one or more waveguides and directed along different beam paths.

Abstract: A two-dimensional waveguide light multiplexer is described herein that can efficiently multiplex and distribute a light signal in two dimensions. An example of a two-dimensional waveguide light multiplexer can include a waveguide, a first diffraction grating, and a second diffraction grating disposed above the first diffraction grating and arranged such that the grating direction of the first diffraction grating is perpendicular to the grating direction of the second diffraction grating. Methods of fabricating a two-dimensional waveguide light multiplexer are also disclosed.

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: A method for providing a composite field of view includes providing two or more input light beams to a scanning mirror and scanning the two or more input light beams using the scanning mirror to provide a plurality of reflected light beams at different angles. Each of the plurality of reflected light beams is configured to provide an image in a respective field of view. The method also includes receiving the plurality of reflected light beams in a waveguide and projecting a plurality of output light beams from the waveguide to form a projected image in the composite field of view. The composite field of view is larger than the respective field of view provided by each of the two or more input light beams.
