Abstract: Apparatus for generating a dynamic structured light pattern for optical tracking in three-dimensional space, comprises an array of lasers, such as a VCSEL laser array, to project light in a pattern into a three-dimensional space; and an optical element or elements arranged in cells. The cells are aligned with subsets of the laser array, and each cell individually applies a modulation, in particular an intensity modulation, to light from the laser or lasers of the subset, to provide a distinguishable and separately controllable part of the dynamic structured light pattern. A method of generating a structured light pattern is disclosed, in which light is provided from an array of lasers, and light is individually projected from subsets of the array of lasers to provide differentiated parts of the structured light pattern.

Abstract: In one embodiment, a system includes at least one projector configured to project a plurality of projected patterns, where a projected lighting characteristic of each of the projected patterns varies over a time period in accordance with an associated predetermined temporal lighting-characteristic pattern, a camera configured to capture images of detected patterns during the time period, and one or more processors configured to: determine, for each detected pattern, a detected temporal lighting-characteristic pattern based on variations in a detected lighting characteristic of the detected pattern, identify a detected pattern that corresponds to one of the projected patterns by comparing at least one of the detected temporal lighting-characteristic patterns to at least one of the temporal lighting-characteristic patterns, and compute a depth associated with the detected patterns based on the one or more of the projected patterns, the detected pattern, and a relative position between the camera and the projector.

Abstract: Embodiments of the present disclosure relate to a projector that is structured to be incorporated into a small form factor electronic device. In some embodiments, the projector is integrated in a depth camera assembly used for eye tracking and/or determining depth of objects in a local area. The projector includes a vertical cavity surface emitting laser (VCSEL) array and a substrate coupled to the VCSEL array. The VCSEL array is a bottom emitting VCSEL array formed with one or more VCSELs. The substrate includes a plurality of optical features to generate one or more SL patterns from the lights that are emitted from the VCSELs.

Abstract: In one embodiment, a system includes at least one projector comprising a plurality of light emitters, where the projector is configured to project a projected pattern comprising a plurality of projected features having different locations; a camera configured to capture an image comprising a detected pattern corresponding to a reflection of the projected pattern; and one or more processors configured to: identify at least one detected feature of the detected pattern, wherein the detected feature corresponds to at least one reflection of the projected features; and activate or deactivate one or more of the light emitters based on the detected feature. The light emitters may be activated or deactivated by determining a detected feature measurement based on the detected feature, and activating or deactivating one or more of the light emitters when the detected feature measurement satisfies a threshold feature measurement condition.
