摘　　要：本文描述了渐变焦眼镜片上的非旋转轴对称非球面的象散分布测量方法，系统地介绍了所采用的泰曼－格林干涉仪和横向剪切干涉仪的两种测量原理与实验装置，并将这两种仪器的测量结果进行了比较．The measuring methods of the astigmatism distribution of an axisymmetrical non-revolving aspherical surface,used in a progressive multi-focal lens, are described in this paper.The principle and the experimental set-up using the Twyman-Green interferometer and the lateral shearing interferometer for measuring the astigmatism distribution are systematically introduced, and the measured values obtained from these two interferometric methods are compared.
