Latest Patents
Fujio Kato holds a patent for a "Method and apparatus for measuring internal index of refraction of preform of optical fiber." This invention relates to a method and system for measuring the internal refractive index of an optical fiber preform with high precision. The internal refractive index is measured from the state of bending of a light ray passing across the optical fiber preform. The refractive index distribution is determined based on the angle of bending of the light ray, calculated from a specific relation between the light ray's start position and detection position. The surface of a light source is scanned by a knife-edge, allowing for the determination of the start position of the detected light ray on the light source.
