Improving the spatial resolution of the light-modulated scalar order parameter allows high-precision manipulation of functional molecules in the liquid crystals. This study shows that the poor resolution caused by the diffusion of azobenzene is overcome through the polymerization of an azobenzene monomer in the nematic phase. The photo-induced spatial variation of birefringence of non-polymerized and polymerized samples is quantitatively investigated under the same stimulating light. The resolution of the non-polymerized sample decays with time, while the polymerized sample can maintain this feature close to that of the stimulating light.

标量阶数参数的光驱动调制，可实现高空间分辨率

改善光调制标量阶数参数的空间分辨率可实现液晶中功能分子的高精度操纵。这项研究表明，通过向列相中偶氮苯单体的聚合可以克服由偶氮苯扩散引起的较差的拆分度。在相同的刺激光下，定量研究了未聚合和已聚合样品的双折射光致空间变异。未聚合样品的分辨率随时间衰减，而已聚合样品可以保持此特征接近刺激光的特征。
