Abstract

In this paper we present a technique to measure the radius of curvature of a test sphere based on the relation between acquired images of a circular cosine fringe pattern and size of virtual image formed on the calibration test surface. Radius of curvature is calculated with the exact equation proposed, using the parameters of the optical setup. Fringe pattern evaluation was performed by locating extrema indices. The mathematical formulation as well as the experimental setup and results are presented. After applying a linear fit algorithm to the data as a method of compensation, obtained results show an error within the tolerance established by the ISO 10343 specifications.

一种测量标定试验球曲率半径的精确方法

本文提出了一种基于获取的圆余弦条纹图像与标定测试表面上形成的虚像大小之间的关系来测量测试球体曲率半径的方法。利用光学装置的参数，用所提出的精确方程计算了曲率半径。通过定位极值指数对条纹模式进行评价。给出了数学公式、实验装置和实验结果。在对数据应用线性拟合算法作为补偿方法后，得到的结果显示误差在ISO 10343规范规定的公差范围内。
