Abstract: Beam steering devices include a laser and a metasurface for dynamic beam shaping of laser light. A steering actuator may adjust a metasurface with respect to a laser to dynamically shape the beam. Lasers in a plurality of lasers may be selectively activated to generate a desired beam shape.

Abstract: An eyebox region is illuminated with first coherent light and second coherent light having a different wavelength than the first coherent light. A first self-mixed interferometer (SMI) signal is generated in response to first feedback light received back from the eyebox region. A second SMI signal is generated in response to second feedback light received back from the eyebox region. Eye data is generated in response to at least the first SMI signal and the second SMI signal.

Abstract: An example apparatus may include a display, a beamsplitter having a first region and a second region, and a reflective polarizer. The reflectance of the second region of the beamsplitter may be appreciably greater than the reflectance of the first region; for example, at least approximately 20% greater. In some examples, the second region may be a peripheral region surrounding a generally centrally located first region. An example apparatus may be configured so that at least some light emitted by the display is transmitted through the first region of the beamsplitter, reflects from the reflective polarizer, reflects from the second region of the beamsplitter, and is then directed through the reflective polarizer to an eye of a user when the user wears the apparatus. Other devices, methods, systems, and computer-readable media are also disclosed.

Abstract: A liquid lens includes a substrate, a transparent elastic membrane forming a cavity with the substrate, and a transparent fluid filling the cavity between the substrate and the membrane. The membrane has a pre-distorted, rotationally asymmetric shape in absence of the fluid in the cavity. When the cavity is filled with the fluid and the substrate is disposed vertically w.r.t. gravity at a pre-defined clocking angle, the membrane adopts a substantially rotationally symmetric shape due to elasticity of the membrane counteracting gravity exerting a downward force on the fluid in the cavity, reducing the effect of the gravity sag on optical performance of the liquid lens.

Abstract: The disclosed apparatus may include a first rigid lens; a second rigid lens, a seal that couples the first rigid lens and the second rigid lens together, where the first rigid lens, the second rigid lens, and the seal define a cavity; and a fluid within the cavity, where the seal is adapted to admit expansions of the fluid within the cavity. Various other apparatuses and methods also disclosed.

Abstract: Angular sensors that may be used in eye-tracking systems are disclosed. An eye-tracking system may include a plurality of light sources to emit illumination light and a plurality of angular light sensors to receive returning light that is the illumination light reflecting from an eyebox region. The angular light sensors may output angular signals representing an angle of incidence of the returning light.

Abstract: A lightguide with partially reflective slanted polarization-selective bulk mirrors is disclosed. The lightguide may be used in a near-eye display with a polarized image source. The polarization-selective bulk mirrors reflect light of the polarized image source, and fully transmit light of the orthogonal polarization, causing the mirrors to be less conspicuous to an external viewer while preserving high efficiency of delivery of the image light to the viewer.

CPC classification number: G02B5/20
Abstract: A notched filter includes a multilayer having alternating first and second polymer layers, the first polymer layers each including an isotropic polymer thin film having in-plane refractive indices n1x and n1y, and the second polymer layers each including an isotropic or anisotropic polymer thin film having in-plane refractive indices n2x and n2y, where a thickness of each successive first polymer layer decreases with increasing distance from a centerline of the multilayer, and a thickness of each successive second polymer layer increases with increasing distance from the centerline. Such a filter may be configured to reflect incident light having a desired polarization state within a predetermined and relatively narrow band.

Abstract: An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. An example apparatus may include a display, a first lens assembly including a lens and a reflector, and a second lens assembly including a second lens and a second reflector. In some examples, the first lens assembly has a front surface configured to receive display light from the display when the display is energized. The first lens assembly may include a Fresnel surface (e.g., a Fresnel surface including facets and steps) that may, for example, be formed in a lens surface, or in the surface of a substrate supported by a lens surface. Other devices, methods, systems and computer-readable media are also disclosed.
