| titleOfInvention | Methods and apparatus for determining geometric properties of optical fiber preforms |
| abstract | A method and apparatus for evaluating the geometric properties of an optical fiber base material, the method comprising: providing an optical fiber base material having a longitudinal axis, an outer diameter and a circumference; Providing a two-dimensional pattern having a length parallel to the longitudinal axis of the base material and a width greater than the outer diameter of the base material; Providing an image capturing device arranged such that the base material is aligned between the pattern and the image capturing device; Rotating the base material around its longitudinal axis and acquiring a first plurality of images of the pattern seen through the base material at at least two different points along the circumference of the base material; And determining at least one geometric property of the base material from the first plurality of images. |
