(Freedman 2010) Essentially, a single infrared beam is split by refraction after exiting a carefully developed lens. This refraction creates a point cloud on an object that is then transmitted back to a receiver on the assembly. Using complex built-in firmware, the Kinect can determine the three-dimensional position of objects in its line-of-sight by this process. (Freedman 2010) The advantage of this assembly (shown below in Figure 1) is that it allows 3D registration without a complex set-up of multiple cameras and at a much lower cost than traditional motion labs and robotic vision apparatuses.
