摘要： PROBLEM TO BE SOLVED: To provide a method for measuring the non-circularity of cores of optical fiber preforms and capable of measuring the non-circularity of cores of optical fiber preforms at high speed.
SOLUTION: In the method for measuring the non-circularity of cores of optical fiber preforms, an optical fiber preform is immersed in a container filled with matching oil. As raising or lowering the optical fiber preform and irradiating light from the side, the width of light transmitted through a core part of the optical fiber preform is measured as a relative outer diameter value of the core part. The width of the light is continuously recorded along longitudinal directions with its positions. Then the optical fiber preform is rotated by a prescribed angle, and similar measured and recording are repeated as lowering or raising the optical fiber preform. On the basis of a longitudinal distribution of a group of relative outer diameter values of the core part acquired at a plurality of angles in circumferential directions, the non-circularity of the core part at each longitudinal position is computed.
