摘要
介绍了用于压平眼压计的圆台压平棱镜进行角膜压平直径线性测量原理及定位偏差分析;着重讨论了光通量补偿及角膜压平面积线性测量原理;也介绍了利用计算机图形学设计和制作通量补偿片的方法。
The linear measurement principle of flattened diameter of the ocular cornea and the location deviation of the cone prism which is used in the applanation tonometer are introduced.The principles of luminous flux compensation for the cone prism and linear measurement of flattened area of the ocular cornea are emphatically discussed.The design and making method of the compensating flake of luminous flux using computer graphics is also introduced.
