Abstract: An eyepiece for projecting an image to a viewer includes a substrate positioned in a substrate lateral plane and a set of color filters disposed on the substrate. The set of color filters comprise a first color filter disposed at a first lateral position and operable to pass a first wavelength range, a second color filter disposed at a second lateral position and operable to pass a second wavelength range, and a third color filter disposed at a third lateral position and operable to pass a third wavelength range. The eyepiece further includes a first planar waveguide positioned in a first lateral plane adjacent the substrate lateral plane, a second planar waveguide positioned in a second lateral plane adjacent to the first lateral plane, and a third planar waveguide positioned in a third lateral plane adjacent to the second lateral plane.

Abstract: A display system includes projection optics configured to project a beam of light in a first direction and an eyepiece unit including a first waveguide layer disposed in a first lateral plane and including an incident light surface and an opposing surface opposite the incident light surface and an incoupling diffractive optical element disposed on the incident light surface. The incoupling diffractive optical element is configured to incouple a first portion of the beam of light and to propagate the first portion of the beam of light by total internal reflection in a second direction and transmit a second portion of the beam of light along the first direction. The eyepiece also includes a retroreflector disposed adjacent the opposing surface. The retroreflector is configured to retroreflect the second portion of the beam of light along a reflected direction opposite to the first direction.

The optical device can include a first surface that is parallel to a horizontal axis and a second surface opposite to the first surface that is inclined with respect to the horizontal axis by a wedge angle. 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 second surface may be inclined such that a height of the light input surface is less than a height of the side opposite the light input surface.

Abstract: A method of reducing optical artifacts includes injecting a light beam generated by an illumination source into a polarizing beam splitter (PBS), reflecting a spatially defined portion of the light beam from a display panel, reflecting, at an interface in the PBS, the spatially defined portion of the light beam towards a projector lens, passing at least a portion of the spatially defined portion of the light beam through a circular polarizer disposed between the PBS and the projector lens, reflecting, by one or more elements of the projector lens, a return portion of the spatially defined portion of the light beam, and attenuating, at the circular polarizer, the return portion of the spatially defined portion of the light beam.

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: In some embodiments, an augmented reality system includes at least one waveguide that is configured to receive and redirect light toward a user, and is further configured to allow ambient light from an environment of the user to pass therethrough toward the user. The augmented reality system also includes a first adaptive lens assembly positioned between the at least one waveguide and the environment, a second adaptive lens assembly positioned between the at least one waveguide and the user, and at least one processor operatively coupled to the first and second adaptive lens assemblies. Each lens assembly of the augmented reality system is selectively switchable between at least two different states in which the respective lens assembly is configured to impart at least two different optical powers to light passing therethrough, respectively. The at least one processor is configured to cause the first and second adaptive lens assemblies to synchronously switch between different states in a manner such that the first and second adaptive lens assemblies impart a substantially constant net optical power to ambient light from the environment passing therethrough.
