摘要： 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.

摘要： 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.

摘要： A light source of a self-mixed interferometer (SMI) emits infrared light. The infrared light is directed to an eyebox location with the scanning module by scanning the infrared light into a waveguide. Feedback infrared light is measured by a light sensor of the SMI.

摘要： An example apparatus may include a display and an optical configuration configured to provide an image of the display. The optical configuration may include a lens having a lens surface that supports at least one serpentine electrode. The at least one serpentine electrode may be in electrical communication with an electrical component such as an electrooptical component (e.g., including at least one of a laser, light-emitting diode, photodiode, or image sensor) or an electroactive component that may show one or more dimensional changes under application of an electric field. An example apparatus may also include a controller in electrical communication with the electrical component through the at least one serpentine electrode. In some examples, the serpentine electrode may have an approximately sinusoidal shape. Other devices, methods, systems, and computer-readable media are also disclosed.

摘要： A method of manufacturing an optically anisotropic polymer thin film includes forming a composite structure that includes a polymer thin film and a high Poisson's ratio polymer thin film disposed directly over the polymer thin film, attaching a clip array to opposing edges of the composite, the clip array including a plurality of first clips slidably disposed on a first track located proximate to a first edge of the composite and a plurality of second clips slidably disposed on a second track located proximate to a second edge of the composite, applying a positive in-plane strain to the composite along a transverse direction by increasing a distance between the first clips and the second clips, and decreasing an inter-clip spacing amongst the first clips and amongst the second clips along a machine direction, wherein the high Poisson's ratio polymer thin film applies a negative in-plane strain to the polymer thin film along the machine.

摘要： 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.

摘要： An optical transformer includes a light source and an array of photovoltaic cells optically coupled to the light source, where at least a portion of the photovoltaic cells are connected in series. An optical connector such as a waveguide or an optical fiber may be disposed between an output of the light source and an input of the array of photovoltaic cells. Configured to generate a high voltage output, the optical transformer may be configured to power a device such as an actuator that provides a tunable displacement as a function of voltage.

摘要： Self-mixed interferometer (SMI) devices and techniques are described for measuring depth and/or velocity of objects. The SMI devices and techniques may be used for eye-tracking. A light source of an SMI sensor emits coherent light that is directed to a target location with a scanning module. One or more SMI signals are measured. The one or more SMI signals are generated by the SMI sensor in response to feedback light received from the target location. The feedback light is a portion of the coherent light that illuminated the target location.
