根据高斯光学原理,以液体透镜为核心元件,研究了无移动镜组变焦系统的设计方法.从医用内窥镜的使用要求出发,设计了一种二元变焦内窥镜系统.该系统可通过气压或液压控制液体透镜表面曲率变化,实现1.5倍变倍比,在1.8 mm和2.7 mm焦距下都获得了良好的成像质量.

Tunable-focus liquid lens is considered as a kind of novel device based on biological vision system,which has many advantages such as little volume and weight,easily to be integrated and active zooming. A method of designing zoom optical system without moving lens is demonstrated according the theory of Gaussian optics,in which the liquid lenses are used as core elements. And a bifocal zoom endoscope system is presented,in which the curvature of the liquid lens can be controlled by air pressure or hydraulic pressure. A zooming factor of 1.5 is realized. And the acceptable imaging quality is gotten at both focal length of 1.8 mm and 2.7 mm of the system.
