| 描述了渐变焦眼镜片的非旋转轴对称非球面表面象散分布测呈,介绍了用泰曼一格林干涉仪和横向剪切干涉议的测量原理和方法,并将这两种仪器的测量结果进行了比较。 |
| 英文摘要: |
| The measuring method of the astigmatism distribution of a progressive specta-cle lens are described in this paper. This lens has an axisymmetrical non-revolving asphericalsurface. The principal and the experimental set-up using the Twyman-Green interferometerand the lateral shearing interferometer for measuring the astigmatism distribution are intro-duced, and these two interferometric methods are compared. |
