Title: Alan M Nakamura: Innovator in Optical Fiber Classification
Introduction
Alan M Nakamura is a notable inventor based in Torrance, CA, who has made significant contributions to the field of optical fiber technology. His innovative approach to classifying optical fiber flaws has led to advancements in the quality and reliability of fiber optics.
Latest Patents
Nakamura holds a patent for an "Automated method of classifying optical fiber flaws." This invention involves a sophisticated process where flaws in an optical fiber are automatically classified by obtaining separate camera images of the fiber illuminated at different angles. The analysis of these images allows for the detection of optical patterns characteristic of various types of flaws. The method includes determining nominal and actual fiber boundaries using noncoherent light, followed by an initial classification based on the differential nature between the two. Further analysis under a side light beam helps distinguish flaws such as splices, external debris, bubbles, internal debris, and uncured buffer. The system can revert to boundary light analysis to characterize a splice once detected, utilizing a combination of diffused backlighting and reflected frontlighting.
