A non-contact scanning system for three dimensional non-contact scanning of a work piece is disclosed for use in various applications including reverse engineering, metrology, dimensional verification and inspection The scanning system includes a scanner carried by an arcuately configured gantry assembly and a fixture for carrying a work piece. The gantry assembly includes a fixed arcuately shaped gantry member and a telescopic arm that is movable in an arcuate direction relative to a rotary table that carries the object to be scanned. A scanner is mounted on the end of the telescopic member and is movable in a radial direction. Objects to be scanned are mounted on a rotary table that is also movable in an X-Y direction or alternatively in the X, Y and Z directions under the control of a motion control subsystem, a machine control user interface subsystem and an image capture.
