摘要

渐进多焦点镜片以其独特的优势崭露头角, 适用人群越来越广泛。为了对其进行快速、精确检测, 提出了一种低成本、装置简单、易操作的渐进多焦点镜片屈光度检测方法。基于透射式条纹偏折法, 通过对镜片引起的光线偏折角进行计算可以快速得到整个镜片屈光度的分布。文中对屈光度检测方法的优缺点进行综述。对透射式条纹偏折法原理进行了分析和研究; 构建了基于透射式条纹偏折法的实验装置, 介绍了系统中的相机标定和相位解算技术; 对渐进多焦点镜片进行屈光度检测实验, 对结果进行分析, 并与VM-2000进行数据对比实验。结果表明该方法能有效、快速地检测渐进多焦点镜片的屈光度分布, 也可推广应用到其他透镜的检测。

Abstract

Progressive additional lenses have emerged with their unique advantages, and are widely used by people. In order to detect it quickly and accurately, a progressive additional lens diopter detection method with low cost, simple device and easy operation is proposed. This method is based on the transmission fringe deflection method, and the distribution of diopter of the whole lens can be quickly obtained by calculating the deflection of light angle caused by the lens. The advantages and disadvantages of diopter detection methods are summarized. Firstly, the principle of transmission fringe deflection method is analyzed and studied. Secondly, the experimental device based on transmission fringe deflection method is constructed, and the camera calibration and phase calculation technology in the system are introduced. Finally, the diopter detection experiment of progressive additional lens is carried out, the results are analyzed and compared with VM-2000. The results show that this method can effectively and quickly detect the diopter distribution of progressive additional lenses, and can also be extended to other lenses.
