摘要
电脑控制式综合验光仪是目前国际上公认的主要验光设备。文中介绍了综合验光仪的光学原理,采用镜片组合屈光度的最佳方法,从技术指标和成本的角度出发分析了几种镜片分布方案,并找到最佳设计方案,通过数据分析和计算,确定了镜片的组合方式,优化镜片组合设计出整个光学系统结构。实际测量结果证明了研制的全自动综合验光仪符合国家计量校准规范要求。使用综合验光仪能够进行完整的视觉功能测试和定量分析,验光方便、快速、准确。
Computer-controlled phoropter is internationally recognized as the major optometry equipment. This article describes the optical principles using the best method of refractive lens combination, and it analyzes the distribution options of several lenses from the technical specifications and the cost to find the best design. It determined the way of tens combination through data analysis and calculation. The whole optical system structure is designed by optimal combination of lenses. Measured results show that the phoropter is accord with national measurement and calibration specifications. By using the phoroper it can finish the function testing and quantitative analysis, conveniently, fast and accurately.
