Abstract: A head-mounted apparatus include an eyepiece that include a variable dimming assembly and a frame mounting the eyepiece so that a user side of the eyepiece faces a towards a user and a world side of the eyepiece opposite the first side faces away from the user. The dynamic dimming assembly selectively modulates an intensity of light transmitted parallel to an optical axis from the world side to the user side during operation. The dynamic dimming assembly includes a variable birefringence cell having multiple pixels each having an independently variable birefringence, a first linear polarizer arranged on the user side of the variable birefringence cell, the first linear polarizer being configured to transmit light propagating parallel to the optical axis linearly polarized along a pass axis of the first linear polarizer orthogonal to the optical axis, a quarter wave plate arranged between the variable birefringence cell and the first linear polarizer, a fast axis of the quarter wave plate being arranged relative to the pass axis of the first linear polarizer to transform linearly polarized light transmitted by the first linear polarizer into circularly polarized light, and a second linear polarizer on the world side of the variable birefringence cell.

Abstract: Disclosed are dimming assemblies and display systems for reducing artifacts produced by optically-transmissive displays. A system may include a substrate upon which a plurality of electronic components are disposed. The electronic components may include a plurality of pixels, a plurality of conductors, and a plurality of circuit modules. The plurality of pixels may be arranged in a two-dimensional array, with each pixel having a two-dimensional geometry corresponding to a shape with at least one curved side. The plurality of conductors may be arranged adjacent to the plurality of pixels. The system may also include control circuitry electrically coupled to the plurality of conductors. The control circuitry may be configured to apply electrical signals to the plurality of circuit modules by way of the plurality of conductors.

Abstract: Examples of light projector systems for directing input light from a light source to a spatial light modulator are provided. For example, an optical device is disclosed which includes a first surface having a diffractive optical element, a second surface normal to the first surface, and a third surface arranged at an angle to the second surface. The third surface may be a beam splitting surface that is reflective to light of a first state and transmissive to light of a second state. The diffractive optical element may receive an input beam made up of light having the first state, and may convert the input beam into at least a first diffracted beam at a first diffraction angle such that the first diffracted beam is directed toward the second surface, is reflected by the second surface toward the third surface via total internal reflection, and is reflected by the third surface in a direction substantially parallel to the first surface.

Abstract: Techniques are described for operating an optical system. In some embodiments, light associated with a world object is received at the optical system. Virtual image light is projected onto an eyepiece of the optical system. A portion of a system field of view of the optical system to be at least partially dimmed is determined based on information detected by the optical system. A plurality of spatially-resolved dimming values for the portion of the system field of view may be determined based on the detected information. The detected information may include light information, gaze information, and/or image information. A dimmer of the optical system may be adjusted to reduce an intensity of light associated with the world object in the portion of the system field of view according to the plurality of dimming values.

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: An optical device may include a wedge-shaped light turning element, a first surface that is parallel to a horizontal axis, a second surface opposite to the first surface that is inclined with respect to the horizontal axis by a wedge angle, and a light module including light emitters. The light module can be configured to combine light emitted by the emitters. The optical device can further include a light input surface that is between the first and the second surfaces and disposed with respect to the light module to receive light emitted from the emitters. The optical device may include an end reflector disposed on a side opposite the light input surface. 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.
