Paper Abstract

This paper describes microscopic holographic interferometry of optical fibers and a new numerical method for determining refractive index profiles. In end-on(axial) holographic interferometry of an optical fiber,we must polish the end-planes optically flat. So,we bent the optical fiber toroidally and measured it by injecting a laser beam toroidally without polishing the end-planes. Furthermore,we developed a numerical method,'TORUS Abel Inversion',for determining refractive index profiles of the whole optical fiber plane.
