Paper Abstract

An optical fiber inspection technique for detecting the following defects is described: hard debris, necks, and bubbles. It is assumed that there is a single predominant defect in the field of view. Two complementary images of a fiber are utilized: in the first image, the fiber is illuminated with white light from the back; in the second, the image is illuminated with a laser from the side and slightly above. Each defect is characterized by its typical appearance in the two images. The complementary images are used to resolve ambiguities and provide redundancy in cases where a defect cannot be clearly identified in one image alone. Due to modular system design, the system can be easily augmented if the manufacturing process introduces new defects. After describing the inspection technique, the authors show results of exercising the system on a number of images.
