Abstract:
1. A non-contact scanning system comprising: a fixture assembly including a rotatable table for carrying a work piece to be scanned, said rotatable table being rotatable about a vertical axis, said rotatable table also mounted to be moveable in at least two linear axis that are perpendicular to said vertical axis; a scanner assembly including a scanner for scanning a work piece disposed on said rotatable table; a gantry assembly disposed adjacent said rotatable table, said gantry assembly comprising an arcuate shaped gantry arm assembly, wherein said gantry arm assembly includes an arcuately shaped radius arm and an arcuately shaped telescopic member, wherein said radius arm and said telescopic member are formed to enable said telescopic member to be received in said radius arm and move in a telescopic manner relative to said radius arm between a retracted position and an extended position to enable said scanner assembly to be moveable along an arcuate path; and a slide assembly including a slide for carrying said scanner, said slide moveably carried relative to said telescopic member which enables said slide to move in radial directions relative to said telescopic member to enable the distance between said scanner and said work piece on said rotatable table to be varied in order to focus said scanner relative to said work piece, said non-contact scanning system formed to create a spherically shaped scanning envelopes of said work pieces on said rotatable table.
