摘要： A pupil-replicating lightguide includes an in-coupling grating structure, an out-coupling grating structure, and a phase compensation layer. The out-coupling grating structure has a spatially varying parameter such as grating duty cycle or grating thickness for evening out out-coupled distribution of light. The spatially varying out-coupling grating parameter disturbs the phase of the propagating image light. The phase compensation layer has a spatially varying optical thickness that compensates that disturbed phase to planarize an optical phase profile of out-coupled light, thereby improving a modulation transfer function of the pupil-replicating lightguide.

摘要： A directional illuminator for a display apparatus includes a switchable diffuser for tuning a divergence of a light beam illuminating a display panel of the display apparatus. The tunable divergence of the illuminating light beam translates into a tunable exit pupil size at the eyebox of the display apparatus, which may be matched to a pupil size of a user’s eye, thus providing a configurable illumination of the eye pupil. A tiltable reflector in an optical path of the illuminating light beam may be used to shift the location of the exit pupil at the eyebox of the display apparatus.

摘要： A field of view of an imaging or ranging device may be increased multiple times by providing a switchable diffraction grating structure upstream of an imaging camera or ranging light source. The switchable diffraction grating changes the angle of propagating of incoming light by a fixed step, enabling the device to switch between several portions of a compound field of view. The switchable diffraction grating structure may be supported by a lightguide that guides the image light or ranging light by a series of reflections from opposed surfaces of the lightguide.

摘要： An illuminator for a display panel includes a slab of transparent material for propagating illuminating light between outer surfaces of the slab, an out-coupler supported by the slab for out-coupling portions of the illuminating light along one of the outer surfaces of the slab, and a tunable microlens array for forming an array of light spots from the out-coupled illuminating light portions downstream of the focusing element for illuminating pixels of the display panel. The array of light spots may be repeated at a distance from the tunable microlens array due to Talbot effect. The display panel may be illuminated in a color-sequential manner, and the tunable microlens array may be used to adjust the focal plane position for each color channel individually.

摘要： An audio system for artificial reality systems is configured to reduce feedback and mitigate entrainment in audio content presented to the user. The audio system utilizes adaptive feedback cancellation processes to reduce feedback. The audio system processes reference signals in a hybrid of the time domain and the frequency domain to achieve rapid convergence with decreased entrainment. The audio system may pre-whiten reference signals and speaker signals and separate the pre-whitened signals into frequency bands using a filter bank. The audio system uses a state space algorithm to generate adaptive filters in each frequency band. The adaptive filters may be applied to the speaker signal to generate a feedback cancelation signal which may be subtracted from the reference signal to decrease feedback.

摘要： Disclosed herein are related to a system and a method for determining an Angle of Approach (AoA) of a device. A first device may receive a report from a second device having a plurality of ultra-wideband (UWB) devices. The report may include a plurality of values comprising an elevation component and an azimuth component of the AoA from the first device. At least some of the plurality of values may be obtained according to measurements between the plurality of UWB devices of the second devices and the at least one UWB device of the first device. The first device may determine an AoA from the second device, using the plurality of values from the report received from the second device.

In one approach, the device transmits the encoded first slice of the plurality of slices to a head wearable display. In one approach, the device transmits the encoded second slice of the plurality of slices to the head wearable display, while the device transmits a portion of the encoded first slice to the head wearable display.
