摘要： Examples of eye-imaging apparatus using diffractive optical elements are provided. For example, an optical device comprises a substrate having a proximal surface and a distal surface, a first coupling optical element disposed on one of the proximal and distal surfaces of the substrate, and a second coupling optical element disposed on one of the proximal and distal surfaces of the substrate and offset from the first coupling optical element. The first coupling optical element can be configured to deflect light at an angle to totally internally reflect (TIR) the light between the proximal and distal surfaces and toward the second coupling optical element, and the second coupling optical element can be configured to deflect at an angle out of the substrate. The eye-imaging apparatus can be used in a head-mounted display such as an augmented or virtual reality display.

摘要： A method of displaying a target light field using an image-replicating combiner is described. The method comprises determining a target light field to be displayed at a viewing location; determining a transfer function describing the propagation of light through the image-replicating combiner between the viewing location and an input location near to an input surface of the image-replicating combiner; determining an input light field by applying the determined transfer function to the target light field; and displaying the input light field at the input location. A display system to display a target light field is also described.

摘要： A method for determining a transformation between frames of reference for two inertial measurement units (IMUs) is disclosed. The transformation includes biases associated with the measurements of each of the IMUs and the extrinsic details can include relative differences in the position and orientation of the IMUs. The IMUs may be mechanically coupled to a frame so that their movements are related. The IMUs can be coupled to a pair of displays in a head-mounted device (e.g., smart glasses) so that a display spacing between for a pair of stereoscopic displays can be accurately determined and adjusted to match the eyes of the user.

摘要： An imaging device includes a light source, a controller, and a camera. The camera generates a captured image by obtaining, in a first cycle, an image of infrared light. The camera also captures an image of infrared light (first light) transmitted through a windshield. The light source emits the infrared light in a second cycle. The second cycle for the emission is longer than the first cycle for the generation of the captured image. The controller generates a third image as a difference between a first image and a second image.

摘要： Methods, systems, and storage media for projecting multi-viewer-specific 3D object perspectives from a single 3D display are disclosed. Implementations may: acquire face and eye region image data of a plurality of viewers within a field of view of at least one camera associated with a 3D-enabled digital display; analyze the eye region image data to determine at least one 3D eye position, at least one eye state, at least one gaze angle, and at least one point-of-regard for at least one viewer relative to at least one camera associated with the 3D-enabled digital display; and calculate a plurality of image projections for display by the single 3D display.
