Abstract

A new concept for the optimization and optical design of miniature digital zoom optics with liquid lens elements is proposed in this research. The liquid lens elements are limited to the discrete configuration in order to obtain the optimal performance for digital zoom. We propose a newly developed digital zoom layout and optimization with a modified genetic algorism (GA) method, in order to meet the demands of a certain specification. The results show that we achieve a successful optical design and the optimization of the digital zoom optics with liquid optics, whose performance is greatly improved up to 48.68%, from the standpoint of on-axis spot size.

摘要

本研究提出了一种用于具有液体透镜元件的微型数字变焦光学器件优化和光学设计的新概念。为了获得数字变焦的最佳性能，液体透镜元件限于离散配置。我们提出了一种新开发的数字变焦布局，并采用改进的遗传算法（GA）进行优化，以满足特定规格的要求。结果表明，我们成功实现了光学设计，并对具有液体光学元件的数字变焦光学器件进行了优化，从轴上光斑尺寸的角度来看，其性能大幅提高了48.68%。
