可调焦液态透镜因具备体积小、成像好、调焦方便等优点而备受瞩目。使用透明的弹性薄膜和光学平板玻璃将一定体积的液体封装在圆柱形的空腔内, 当空腔内的液体体积变化时, 透镜的曲率半径随之而改变, 实现了透镜的可调焦。实验表明, 该可调焦液态透镜有较好的成像效果, 在一定液体体积变化范围内符合薄透镜成像的规律, 在通讯、**、医疗等方面具有较好的应用前景。

The variable-focus liquid lens, which has the outstanding advantages of little volume, good imaging quality, easily tunable of focal length, etc., is most attractive. In this experiment, transparent elastic membrane and optical glass are used to seal certain volume of liquid in a cylindrical cavity. When the volume of cavity fluid changes, the radius of curvature is also changes, that is, the focus length of the lens can be changed. The experiments show that this kind of variable-focus liquid lens has better image quality, and complies with the law of thin lens imaging within a certain range of changes in liquid volume. Therefore, it has a good future in communications, national defense, medical treatment, etc.
