Abstract: An optical assembly for a digital projector includes a lens and a field bias optical element. The lens is disposed to receive display light generated by a display and to direct the display light along an optical path. The lens is configured to provide a first field-of-view. The field bias optical element is disposed between the lens and an aperture stop of the optical assembly. The field bias optical element is configured to bias the display light in at least one direction to provide a second field-of-view that is greater than the first field-of-view.

Abstract: A system tracks eye movement using optical coherence in a head mounted display. The system includes an illumination source configured to project low coherence interference light onto a portion of a user's eye. The system includes a scanning system to select an axial position within the illuminated portion of the user's eye. The system includes a detector configured to collect light reflected from the illuminated portion of the user's eye at the selected axial position, and the reflected light includes measurement data characterizing the illuminated portion of the user's eye. The system includes a controller configured to compare the measurement data with a trained baseline, and determine an eye position based the comparison.

Abstract: A near-eye display (NED) includes a source assembly, a waveguide outside a field-of-view of a user, and a main optic within the field-of-view. The waveguide expands light emitted from the source assembly in at least one dimension and out-couple the expanded light. The main optic is partially transparent and is positioned such that the user of the NED looks through the main optic to view a local area surrounding the NED. The main optic receives light from the local area, combines the received light with the expanded light to generate combined light, and directs the combined light to the user's eye-box.

Abstract: A retinal imaging system includes a projector, an imaging device, and a controller coupled to an eye tracking system under test. The projector emits a light pattern to be delivered to a pupil of an eye, a location of the pupil being estimated by the eye tracking system under test. The imaging device captures one or more images of a retina of the eye illuminated with at least a portion of the light pattern. The controller determines one or more eye tracking parameters based on the captured one or more images of the retina. The controller compares each determined eye tracking parameter with each of estimated one or more eye tracking parameters, wherein values for the one or more eye tracking parameters are estimated by the eye tracking system under test. The controller characterizes each estimated eye tracking parameter based on the comparison.

Abstract: A head-mounted-display includes an electronic display emitting image light and a varifocal block receiving the image light and outputting the image light in at least one of the focal planes of the varifocal block. The varifocal block includes a back optical element, a front optical element, and an actuator assembly coupled to the back and front optical element. The front optical element is positioned closer to an exit pupil than the back optical element, and separated from the back optical element by an adjustable distance, the magnitude of which determines in which of the focal planes the image light is presented. The actuator assembly simultaneously adjusts positions of the back optical element and the front optical element to vary the adjustable distance between the back optical element and the front optical element in accordance with an estimated vergence depth of the user.

Abstract: A depth camera assembly for depth sensing of a local area includes an illumination source, an imaging device, and a controller. The illumination source illuminates a local area with light emitted in accordance with emission instructions generated by the controller. The illumination source includes an array of optical sources and an optical assembly. Operation of each optical source in the array is controllable based in part on the emission instructions. The optical assembly is configured to project the light into the local area. The imaging device captures one or more images of at least a portion of the light reflected from one or more objects in the local area. The controller determines depth information for the one or more objects based in part on the captured one or more images.
