ABSTRACT:
A zone analysis system and method (211) optimize speed and minimize adverse effects resulting from noise in an inspection system (90) for measuring disparity between two surfaces. In particular, the zone analysis system and method (211) can be implemented in an inspection system (90) for contactlessly measuring undercut or protrusion of an optical fiber (26) relative to a surrounding support material (36) at the endface (79) of an optical fiber termination (37). In structure, the inspection system (90) has a measurement apparatus (91) with an interferometer (98) controlled by a machine vision system (92) for determining the degree of disparity. The inspection system (90) measures an offset of an interferometric fringe (113') produced by the interferometer (98) over the target (82) in the image in order to determine the disparity. Further, the machine vision system (92) employs the zone analysis system and method (211) for optimizing the performance thereof.
