提出了一种在绿光波段通过不对称光对准调制甲基红（MR）掺杂胆甾酯液晶指纹结构的简便方法，从而产生电压可控的螺旋超结构。磁共振分子与入射光偏振之间的相互作用决定了初始的扭曲平面几何形状，通过施加适当的电场对指纹纹理的条纹方向提供了多变量控制。本文从理论和实验上分析了影响指纹条纹可预测和可重写的关键因素，包括排列不对称性、细胞间隙与自然基音长度的比值以及手性掺杂剂的手性。利用两束正交圆偏振和正交线性偏振光的一步偏振全息技术，进一步展示了虚线曲线和虚线形状的动态周期性指纹纹理。相信本研究所描述的实用方法将丰富利用软液晶构件自组装分层超结构的研究内容。提出了一种在绿光波段通过不对称光对准调制甲基红（MR）掺杂胆甾酯液晶指纹结构的简便方法，从而产生电压可控的螺旋超结构。磁共振分子与入射光偏振之间的相互作用决定了初始的扭曲平面几何形状，通过施加适当的电场对指纹纹理的条纹方向提供了多变量控制。本文从理论和实验上分析了影响指纹条纹可预测和可重写的关键因素，包括排列不对称性、细胞间隙与自然基音长度的比值以及手性掺杂剂的手性。利用两束正交圆形和正交直线光束的一步偏振全息技术，进一步展示了虚线和虚线形状的动态周期性指纹纹理。
A convenient approach to modulate the fingerprint textures of methyl red (MR) doped cholesteric liquid crystals by asymmetric photoalignment in the green-light waveband is presented, resulting in the generation of voltage-controllable helical superstructures. The interaction between the MR molecules and the incident light polarization determines the initial twisted planar geometry, providing a multivariant control over the stripe directions of fingerprint textures by applying a proper electric field. The key factors for precise manipulation of fingerprint stripes in a predictable and rewritable manner are analyzed theoretically and investigated experimentally, which involves the alignment asymmetry, the ratio of cell gap to natural pitch length, and the chirality of chiral dopant. Dynamic periodic fingerprint textures in shapes of dashed curve and dashed line are further demonstrated by utilizing a facile one-step polarization holography process using two beams with orthogonal circular and orthogonal linear polarizations, respectively. It is believed that the practical approach described in this study would enrich the research contents of self-assembled hierarchical superstructures using soft liquid crystal building blocks.A convenient approach to modulate the fingerprint textures of methyl red (MR) doped cholesteric liquid crystals by asymmetric photoalignment in the green-light waveband is presented, resulting in the generation of voltage-controllable helical superstructures.
