Abstract
A three-dimensional (3D) sensing apparatus together with a projector subassembly is provided. The 3D sensing apparatus includes two cameras, which may be configured to capture ultraviolet and/or near-infrared light. The 3D sensing apparatus may also contain an optical filter and one or more computing processors that signal a simultaneous capture using the two cameras and processing the captured images into depth. The projector subassembly of the 3D sensing apparatus includes a laser diode, one or optical elements, and a photodiode that are useable to enable 3D capture.
