Abstract
To address the problem of voltage gradient and phase distribution non-uniformity in traditional comb-electrode liquid crystal(LC)lens,this study designs a electrode structure to improve optical performance.By optimizing the electrode layout without increasing the number of driving voltages,the issue of uneven voltage distribution between adjacent electrodes is resolved.The novel and conventional electrode LC lens samples were fabricated via photolithography.Their wavefront patterns and root-mean-square(RMS)errors were then analyzed through interferometry.Finally,the phase distribution and imaging performance of the LC lenses were analyzed.The results show that the novel electrode structure eliminates voltage gradient unevenness.The wavefront pattern exhibits a regular circular distribution,with wavefront RMS reduced by approximately 19.4%compared to the conventional structure.Both phase distribution and imaging performance are improved.This study confirms the effectiveness of electrode structure optimization in enhancing LC lens performance,and offers a technical approach for developing high-precision tunable-focus optical devices.关键词
