摘要

The purpose of this study is to evaluate sectional curves on a progressive lens by using a contact type form measuring equipment. Characteristics of the proposed method is to be able to compensate six setting errors of a specimen. The setting errors are x,y,z-directional components and rotational components around x,y,z-axes. The algorism to search the errors is based on simplex method which is robust to multi-polarity of the objective function. The function is composed of the sum of square deviations between measured data and reference model data.
