A non-contact scanning system is disclosed for three dimensional non-contact scanning of a work piece for use in various applications including reverse engineering, metrology, dimensional verification and inspection The scanning system includes a scanner assembly, a gantry assembly and a fixture assembly. The gantry assembly and the fixture assembly are carried by a table or base. The scanner assembly is carried by the gantry assembly. The fixture assembly is rotatable about two (2) orthogonal axes axis under the control of a control system. The fixture assembly optionally allows the height of the fixture assembly to be adjusted relative to the plane of the table by way of rectilinear movement. The scanning system provides a spherically shaped scanning envelope which facilitates three dimensional modeling of a work piece. 1. A non-contact scanning system comprising:a fixture assembly for carrying a work piece, the fixture assembly having three degrees of freedom;a scanner for scanning the work piece; anda gantry assembly for carrying the scanner, said gantry assembly including a radius arm formed in a generally arcuate shape for use in creating spherically shaped scanning envelopes.2. The non-contact scanning assembly as recited in claim 1 , wherein said fixture assembly is formed to be movable along two rectilinear axes that are perpendicular to each other.3. The non-contact scanning assembly as recited in claim 1 , wherein said fixture assembly is formed to be rotatable about two axes that are perpendicular to each other.4. The non-contact scanning assembly as recited in claim 2 , wherein said fixture assembly is formed to be rotatable about a third axis.5. The non-contact scanning assembly as recited in claim 4 , wherein said third axis is generally perpendicular to said two axes.6. The non-contact scanning assembly as recited in claim 3 , wherein said fixture assembly is formed to be movable in a rectilinear manner along a fourth axis.7. The non-contact scanning ...
