This research illustrates the growth and optimization of mesoscopic liquid crystal superstructures,the generation of vector structured beam arrays,and the application of microlens imaging.Utilizing photoalignment technology,we perform hierarchical control of liquid crystal molecular arrangements from the nanoscale layers to microscale domains and,ultimately,to superstructure arrays.Specifically,we design and optimize the quality of smectic liquid crystal toric focal conic superstructures within the cells.This approach allows us to generate and characterize radially polarized vector beam arrays with a polarization order of P=2.Furthermore,we explore the multifunctional application potential of toric focal conic domain arrays as microlens arrays.Our research integrates the topological properties of liquid crystal microstructures with the structured light fields'topological characteristics,leveraging the unique self-assembly capabilities of liquid crystal materials.This integration not only enables the generation,modulation,and detection of specially structured light fields but also suggests potential innovative applications in precision control fields,such as optical trapping,microfluidic control,and high-resolution imaging.
