A method and apparatus are provided for inspecting an end face of an optical fiber. The apparatus includes a memory device for storing images of acceptable end faces and unacceptable end faces, and an imaging system for obtaining an image of the end face of the optical fiber. Further, the apparatus includes a means, responsive to said imaging system, for comparing the image of the end fare of the optical fiber with the images of acceptable end faces and unacceptable end faces to automatically determine if the optical fiber is acceptable.

Automatic fiber optic connectorization and inspection system (AFOCIS)

A fastener for use in connecting first and second structural members together. The first and second members have aligned bores defining a fastener receiving hole including a countersink portion extending from an outer surface of the first member and a through portion extending from an inner end of the countersink portion to an inner surface of the first member. The through portion has a mouth at its intersection with the countersink portion. The fastener comprises a head having a shape which is different than the shape of the countersink portion when the head is in an undeformed condition. A shank extends from the head and is dimensioned to be received through the through portion of the fastener receiving hole and to extend outwardly from the bore of the second member when the head is in contact with the first member in the countersink portion. The head is constructed for plastic deformation upon force being applied thereto such that substantial cold working of the material of the head occurs at the mouth of the through portion and the head assumes a shape complementary to that of the countersink portion to provide a uniform fill of the countersink and through portions of the bore of the first member.
