    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: Architectures are provided for selectively outputting light for forming images, the light having different wavelengths and being outputted with low levels of crosstalk. In some embodiments, light is incoupled into a waveguide and deflected to propagate in different directions, depending on wavelength. The incoupled light then outcoupled by outcoupling optical elements that outcouple light based on the direction of propagation of the light. In some other embodiments, color filters are between a waveguide and outcoupling elements. The color filters limit the wavelengths of light that interact with and are outcoupled by the outcoupling elements. In yet other embodiments, a different waveguide is provided for each range of wavelengths to be outputted. Incoupling optical elements selectively incouple light of the appropriate range of wavelengths into a corresponding waveguide, from which the light is outcoupled.

    Abstract: Systems and methods for eye pose identification using features of an eye are described. Embodiments of the systems and methods can include segmenting an iris of an eye in the eye image to obtain pupillary and limbic boundaries of the eye, determining two angular coordinates (e.g., pitch and yaw) of an eye pose using the pupillary and limbic boundaries of the eye, identifying an eye feature of the eye (e.g., an iris feature or a scleral feature), determining a third angular coordinate (e.g., roll) of the eye pose using the identified eye feature, and utilizing the eye pose measurement for display of an image or a biometric application. In some implementations, iris segmentation may not be performed, and the two angular coordinates are determined from eye features.

    Abstract: A display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity may be selected using an array of shutters that selectively regulate the entry of image light into an eye. Each opened shutter in the array provides a different intra-pupil image, and the locations of the open shutters provide the desired amount of parallax disparity between the images. In some other embodiments, the images may be formed by an emissive micro-display. Each pixel formed by the micro-display may be formed by one of a group of light emitters, which are at different locations such that the emitted light takes different paths to the eye, the different paths providing different amounts of parallax disparity.

    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 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 third surface and is reflected by the third surface in a direction substantially parallel to the first surface.

    Abstract: An eyepiece waveguide for an augmented reality. The eyepiece waveguide can include a transparent substrate with an input coupler region, first and second orthogonal pupil expander (OPE) regions, and an exit pupil expander (EPE) region. The input coupler region can be positioned between the first and second OPE regions and can divide and re-direct an input light beam that is externally incident on the input coupler region into first and second guided light beams that propagate inside the substrate, with the first guided beam being directed toward the first OPE region and the second guided beam being directed toward the second OPE region. The first and second OPE regions can respectively divide the first and second guided beams into a plurality of replicated, spaced-apart beams. The EPE region can re-direct the replicated beams from both the first and second OPE regions such that they exit the substrate.
