Abstract: Examples of a wearable device are disclosed. In one example, the wearable device may include an optical network, a first sensor and a second sensor coupled with the optical network, and a processor. The first sensor and a second sensor are configured to generate, respectively, first sensor data and second sensor data related to different physical measurements, and to transmit the first sensor data and the second sensor data to the optical network. The processor is coupled with the optical network and configured to: receive at least one of the first sensor data or the second sensor data from the optical network; and determine output content of the wearable device based on the at least one of the first sensor data or the second sensor data.

Abstract: A depth camera assembly (DCA) includes a projector, a detector and a controller. The projector emits a tiled structured light (SL) pattern onto a local area. Each illumination source of the projector includes one or more light emitters and an augmented diffractive optical element (ADOE) designed with a pattern mask. The ADOE diffracts at least a portion of light beams emitted from the light emitters to form a first SL pattern projection having a field-of-view corresponding to a first tileable boundary. The pattern mask prevents projection of light that would otherwise be diffracted outside the first tileable boundary. The first SL pattern projection is combined with at least a second SL pattern projection into the tiled SL pattern illuminating objects in the local area. The detector captures images of the objects illuminated by the SL pattern. The controller determines depth information for the objects using the captured images.
