Abstract: Sensing apparatus includes a projector, which projects toward a target a pattern of spots extending over a predefined angular range about a projection axis. An imaging assembly includes an image sensor and objective optics, which form on the image sensor an image of the target along an imaging axis, which is offset transversely relative to the projection axis. A processor is configured to process signals output by the image sensor so as generate, while the target is within a first span of distances from the apparatus, a depth map of the target responsively to shifts of the spots in the image, and to estimate, while the target is within a second span of distances, nearer to the apparatus than the first span, a distance to the target from the apparatus by detecting in the image a part of the pattern located at an edge of the angular range.

Abstract: Various embodiments disclosed herein include devices, systems, and methods for spatially controlling illumination provided by a flash module. The flash module includes a flash controller that controls light emitters of an emitter array according to an illumination profile. The illumination profile is selected to reduce a relative brightness to a target region of the flash module's field of illumination. The target region is associated with a portion of a target object identified in the field of illumination. In some instances, the target region corresponds to a portion of a user's eye that is positioned within the field of illumination. In other instances, the flash module is incorporated into a device, and the target region corresponds to a reflected image of a portion of the device that is positioned within the field of illumination.
