Abstract: A display device includes a display panel having a first emission region and a second emission region that surrounds the first emission region. The display device includes a first plurality of light emitters arranged in the first emission region, a plurality of activation lines for the first emission region, a second plurality of light emitters arranged in the second emission region, and a plurality of activation lines for the second emission region. A single activation line of the plurality of activation lines for the first emission region is electrically coupled with a first number of light emitters in the first emission region and a single activation line of the plurality of activation lines for the second emission region is electrically coupled with a second number, distinct from the first number, of light emitters in the second emission region.

Abstract: Techniques disclosed herein relate to a near-eye display system. One example of an eye-tracking system includes a substrate transparent to visible light and infrared light and a reflective holographic grating conformally coupled to a surface of the substrate. The reflective holographic grating is configured to transmit the visible light and reflectively diffract infrared light in a first wavelength range for eye tracking. The refractive index modulation of the reflective holographic grating is apodized in a direction along a thickness of the reflective holographic grating to reduce optical artifacts in the visible light.

Abstract: 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.

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: An optical device includes a first polarization selective reflector; a second polarization selective reflector positioned relative to the first polarization selective reflector so that the first polarization selective reflector directs first light having a first nonplanar polarization toward the second polarization selective reflector and the second polarization selective reflector directs at least a portion of the first light toward the first polarization selective reflector as second light. The optical device includes a first reflector positioned relative to the first polarization selective reflector so that the first polarization selective reflector directs at least a portion of the second light having a second nonplanar polarization toward the first reflector as third light.

Abstract: 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.

Abstract: An off-axis optical combiner includes a parabolic lensing structure that selects collimated infrared image light received from an eyebox area for focusing to a focus of the off-axis optical combiner. Selecting the collimated infrared image light for focusing allows the parabolic lensing structure to form a same-sized image of an object having variable depth from the parabolic lensing structure.

Abstract: 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.
