Abstract

A stacked liquid lens based on electrowetting-on-dielectric (EWOD) is designed to analyze the ability of correcting the distorted wavefront caused by curvature, tilt, and piston. The model of the stacked liquid lens is constructed by COMSOL software which is used to simulate the change of liquid interface with different voltage combinations, and the change range of the interface. The correction ability of the stacked liquid lens at a certain point in the wavefront is assessed from wavefront image and point spread function (PSF) is got by ZEMAX software. The results show that different types of distorted wavefront can be compensated via the stacked liquid lens. The peak-to-valley (PV) value decreases from 19.7853 to 0.18, and the root mean square (RMS) value is down from 5.6638 to 0.0355. Concurrently, the Strehl ratio (SR) increased from near 0 to 0.962. The related research results have broad prospects in the field of wavefront correction.

基于介质电润湿的叠置液体透镜波前校正特性

设计了一种基于介质电润湿(EWOD)的叠置液体透镜，分析了曲率、倾斜和活塞引起的畸变波前的校正能力。利用COMSOL软件建立了叠层液透镜的模型，模拟了不同电压组合下液界面的变化，以及界面的变化范围。从波前图像评估叠液透镜在波前某一点的校正能力，并利用ZEMAX软件得到点扩散函数(PSF)。结果表明，叠置液体透镜可以补偿不同类型的畸变波前。峰谷(PV)值从19.7853下降到0.18，均方根(RMS)值从5.6638下降到0.0355。Strehl比(SR)由接近0提高到0.962。相关研究成果在波前校正领域具有广阔的应用前景。
