PROBLEM TO BE SOLVED: To provide an optical edge break gage capable of performing inspection rapidly and accurately. SOLUTION: A projector 20 projects a structured light pattern 46 along a first optical axis 44 onto a surface 80. A viewer 50 attached to the projector 20 receives a reflection of the structured light pattern 46 from the surface 80 along a second optical axis 54, and digitizes a two-dimensional snapshot. A computer 61 interfaced to the viewer 50 receives the digitized snapshot, and analyzes it to mathematically model the surface for display and inspection. The projector and attached viewer are designed as a hand-held unit with a hand grip 66 and a trigger button 68 to trigger a snapshot. A guide tip arranged on the hand-held unit extends beside the two optical axes 44, 54 to the common field of view to position the hand-held unit. COPYRIGHT: (C)2007,JPO&INPIT |
