本文介绍了一种计算机辅助无损测量光纤预制棒任意二维折射率分布的方法。预制件中光线的折射角由光学装置测量，该光学装置的特征在于使用三角形掩模将光线的角度转换为它们的位移。根据这些折射角的信息计算折射率分布。
A nondestructive computer-aided measurement of the arbitrary two-dimensional refractive-index distribution of an optical fibre preform is described. The angle of refraction of rays in the preform is measured by an optical set-up which features the use of a triangular mask for converting the angle of rays to their displacement. The index distribution is computed from the information on these refraction angles.
