ABSTRACT:
An 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 or discontinuity of one surface relative to another surface, particularly the amount of undercut or protrusion of an optical fiber (26) relative to an adjacent surrounding termination plug (36) in an optical fiber termination (37). The machine vision system (92) employs an inspection control algorithm (120) that is reliable, accurate, and user friendly. Moreover, the machine vision system (92) can receive prompts from a user via an input device (94), such as a keyboard, and can transfer information to the user via an output device (93), such as a display, and/or to another system.
