Abstract: An optical assembly is configured to receive visible scene light at the backside of the optical assembly and to direct the visible scene light on an optical path toward the eyeward side. The optical assembly includes a dimming element disposed on the optical path, wherein the dimming element includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. An illuminator, coupled to an edge of the dimming element, is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of the photochromic material to dim the visible scene light.

Abstract: Techniques disclosed herein relate generally to eye-tracking in near-eye display systems. One example of an eye illuminator for eye-tracking includes a substrate transparent to visible light, an array of light sources immersed in the substrate and configured to emit infrared light, and a holographic optical element conformally coupled to a surface of the substrate and encapsulated by an encapsulation layer. The holographic optical element is configured to transmit the visible light and diffract the infrared light emitted by the array of light sources to the eye of a user for eye-tracking.

Abstract: A device includes a light source, a waveguide layer, and a light director layer. The light source emits illumination light. The waveguide layer includes a cladding layer and an optical waveguide. The cladding layer provides a top planar surface of the waveguide layer and the optical waveguide is immersed in the cladding layer and includes a light input coupler. The light director layer includes a bottom planar surface that is disposed on the top planar surface of the waveguide layer. The light director layer also includes a light director that receives and directs the illumination light to the light input coupler as shaped light. The light director is configured to tilt the illumination light to give the shaped light a tilt angle with respect to the light input coupler.

Abstract: A plurality of light sources such as vertical-cavity surface-emitting lasers (VCSELs) are configured to emit light through emission apertures. The light may be near-infrared light. Optics are formed over the emission apertures of the plurality of light sources. The optics may provide different tilt angles or divergence angles to the non-visible light emitted by the light sources in the plurality of light sources.

Abstract: The disclosed embodiments are generally directed to optical systems. The optical systems may include a proximal lens that may transmit light toward an eye of a user. The optical systems may also include a distal lens that may, in combination with the proximal lens, correct for at least a portion of a refractive error of the eye of the user. The optical systems may further include a selective transmission interface. The selective transmission interface may couple the proximal lens to the distal lens, transmits light having a selected property, and does not transmit light that does not have the selected property. The optical system can also include an accommodative lens, such as a liquid lens. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The disclosure includes optical systems and near-eye optical elements configured to suppress stray infrared light. Infrared illuminators illuminator an eyebox area with narrow-band infrared illumination light for eye-tracking. A combiner layer receives reflected infrared light reflected of an eye of the user and directs the reflected infrared light to a camera configured to capture eye-tracking images of an eye of a user. An anti-reflection (AR) coating may be disposed on a base curvature to reduce Fresnel reflections that generate stray light. A ghost suppression component may be paired with the infrared illuminators to reduce stray light becoming incident on the camera.

Abstract: A method for calibrating eye tracking data for a head wearable optical device includes receiving eye tracking data from an imaging device oriented towards a combiner. The method includes determining a gaze direction of an eye of a user based on the eye tracking data. The method includes receiving calibration data from the imaging device that includes an indication of positions of one or more calibration indicators. The method includes determining the gaze direction based at least in part on the calibration data received from the imaging device (or factors adjusted by the calibration data).
