Paper Abstract

We demonstrate a novel method which is simple, real-time, and non-destructive to measure the core diameter of a coaxial cylinder. An optical fiber is an example of coaxial cylinder. The diameter measurement method is based on side-light-incidence scattering principle. For a cladding diameter 126μm coaxial fiber, our method could be used to measure core diameter ranging from 8 to 40μm. We could measure the core diameter of a coaxial cylinder for cladding diameter varying from 50 μm to 125 μm from our database. The accuracy of core diameter measurement could reach over 95%.
