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. 1. An apparatus for depth sensing , the apparatus comprising: a lens, and', 'an optical filter passing a spectrum of wavelengths;, 'at least two near-infrared (NIR) or ultraviolet (UV) cameras, wherein each of the NIR or UV cameras includea projector that projects light such that an epipolar search is performable on scanlines; and initiate the at least two NIR or UV cameras to simultaneously capture images, and', '(i) process the simultaneously captured images into depth and transmit depth data to a host processor or (ii) transmit the simultaneously captured images to a host processor for processing into depth., 'one or more computing processors that2. The apparatus of claim 1 , wherein an exit pupil of the projector lies on a line containing a focal point of the at least two NIR or UV cameras.3. The apparatus of claim 1 , wherein the projector projects light down optical axes of the at least two NIR or UV cameras.4. A method for sensing depth claim 1 , the method comprising:using at least two near-infrared (NIR) or ultraviolet (UV) cameras to simultaneously capture one or more images;performing stereo to the simultaneously captured one or more images by:(i) selecting a point in one image of the simultaneously captured one or more images,(ii) computing, by a computing processor, a matching score along an epipolar line in another of the simultaneously captured images,(iii) minimizing the matching score ...
