The Zeiss slit lamp has been modified in order to extend its use to measurements of lens transparency. Two major modifications have been introduced: (1) a support for a high-sensitivity TV camera that is connected to an image processing system; (2) two potentiometers for recording electrical signals proportional to the rotation angle of the slit-supporting arm with respect to the visual axis and the slit tilting angle. As a result, the slit lamp output consists of three signals; one TV signal for the images and two analog signals for measurement of the angles. With the aid of an image-processing system connected to a minicomputer, software has been developed to enable the operator to acquire reliable digital images of the anterior segment of the eye in real time. The software provides the user with an easy-to-follow menu.
蔡司裂隙灯已进行了改进，以便将其用途扩展到晶状体透明度的测量。已进行了两项主要改进：（1）为连接到图像处理系统的高灵敏度电视摄像机提供一个支架；（2）两个电位计，用于记录与裂隙支撑臂相对于视轴的旋转角度以及裂隙倾斜角度成比例的电信号。结果，裂隙灯输出由三个信号组成；一个用于图像的电视信号和两个用于角度测量的模拟信号。借助连接到小型计算机的图像处理系统，已开发出软件，使操作员能够实时获取眼部前段的可靠数字图像。该软件为用户提供了一个易于操作的菜单。
