摘　　要：设计了一种医用内镜图像显示双通道光学接口。接口由分光棱镜和变焦距物镜组成。本文介绍光学接口的分光及光孔承接；分析变焦物镜的光学特性；论述小型线性差动变焦物镜的设计原理；并给出了一种设计实例及评价结果。所设计的光学接口已应用于胃镜计算机彩色显微图像显示仪中。使用证明：该光学接口结构简单、体积小、重量轻，其像质可与多种内镜和 Ｃ Ｃ Ｄ 彩色摄像机相匹配。因此，接口可适用于多种内镜的图像显示。A double passage optical interface for displaying medical endoscope image was designed. The interface was composed of a prism and a zoom lens. The followings were presented: the light splitting and aperture matching of the interface, optical property of the zoom lens, the principle of miniature linear differential zoom lens design. An example of design and its evaluation were also given. The interface designed had been used in a computer system for displaying endoscope image, and was proved to be simple, small and light enough. With its good performance, the interface may be used in the matching of CCD cameras with several kinds of endoscopes. So the interface may be used for displaying several kinds of endoscopes images.
