| 中文摘要: |
| 变焦光学系统是照相机、摄像机等许多光学器件中的关键元件，实现变焦光学系统的微小型化及增大系统的变倍比是一个长期目标。研制了一种三液体自变焦补偿透镜，可在外加电压作用下实现自变焦补偿功能，因此该透镜元件本身可以作为一个简单的变焦光学系统。通过高斯光学理论分析及Zemax模拟仿真验证了该系统的自变焦补偿功能。结果表明，该系统焦距变化范围为378～424 mm，变倍比为1.217，达到了预期目标，对变焦光学系统的研究具有一定的参考价值。 |

| Optical zoom system is a key element in many optical devices such as cameras and video cameras. It is a long-term goal to realize miniaturization of optical zoom system and increase the zoom ratio of the system. In this paper, a three-liquid self-zoom lens is developed, which has the self-zoom function under the action of applied voltage. Therefore, the lens element itself can be used as a simple optical zoom system. The self-zoom function of the system is verified by the Gaussian optical theory and Zemax simulation. The results show that the focal length range of the system is 378-424 mm, and the zoom ratio is 1.217, which achieves the expected target and has a certain reference value for the research of optical zoom systems. |
