一种基于液体透镜的全息色差补偿方法
A Method of Holographic Chromatic Aberration Compensation Based on a Liquid Lens
摘要
在真彩色全息显示中,由波长不同引入的色差往往会影响再现像的观看效果。利用液体透镜的可变焦特性,提出了一种基于液体透镜的全息色差补偿方法。利用电湿润原理制作了一个液体透镜,当改变液体透镜的电压时,它的焦距也会随之改变。当三种颜色的激光时序照射相应颜色的全息图时,通过控制液体透镜的焦距相应地改变,从而使三种颜色的再现像清楚地呈在同一位置。实验结果表明了该方法的可行性。
Abstract
In the color holographic display, the quality of reconstructed images are affected by chromatic aberration caused by different wavelengths of color lasers. Using the zoom feature of the liquid lens, a method of holographic chromatic aberration compensation based on a liquid lens is proposed. A liquid lens using the principle of electrowetting is developed. When the voltage applied to the liquid lens changes, the focal length changes accordingly. When three color lasers illuminate the corresponding holograms in turns, by keeping the focal length of the liquid lens change accordingly, three color reconstructed images can display in the same location clearly. The experimental results verify its feasibility.
