    • A corneal topographer includes: a flat panel display configured to display a light pattern and to project the light pattern onto a cornea of an eye disposed on a first side of the flat panel display; an optical system disposed on a second side of the flat panel display, the optical system being configured to receive and process reflected light from the cornea that passes through the flat panel display from the cornea to the optical system; a camera configured to receive the processed reflected light from the optical system and to capture therefrom a reflected light pattern from the cornea produced in response to the projected light pattern; and one or more processors configured to execute an algorithm to compare the projected light pattern to the reflected light pattern from the cornea, and to produce a topographic map of the cornea based on a result of the comparison.
    • 角膜地形图仪包括:平板显示器,被配置为显示光图案并且将光图案投影到布置在平板显示器的第一侧上的眼睛的角膜上; 设置在所述平板显示器的第二侧上的光学系统,所述光学系统被配置为接收并处理来自角膜的反射光,所述角膜从角膜穿过平板显示器到达光学系统; 相机,其被配置为接收来自光学系统的经处理的反射光并且从其捕获来自响应于投影的光图案而产生的角膜的反射光图案; 以及一个或多个处理器,被配置为执行算法以将投影的光图案与来自角膜的反射光图案进行比较,并且基于比较结果产生角膜的地形图。
