论文摘要
在许多现代应用中，光束的塑形和转向至关重要，从光学镊子，相机镜头，视觉校正到3D显示器。但是，当前的实现需要越来越高的可调节性，并旨在使在不同应用中使用的特异性较小。在这里，我们使用理论和完整的数值建模的组合，基于多层液体晶体细胞和外部电场演示可调的光束控制，能够扩展光束移动，转向和扩展。具体而言，通过利用三个不同功能特异性和可调的双发性夜间夜间层，我们显示了一个有效的液晶束控制装置，能够精确控制外向光传播，并可能在投影仪或自动动力头灯中应用。
Shaping and steering of light beams is essential in many modern applications, ranging from optical tweezers, camera lenses, vision correction to 3D displays. However, current realisations require increasingly greater tunability and aim for lesser specificity for use in diverse applications. Here, we demonstrate tunable light beam control based on multi-layer liquid-crystal cells and external electric field, capable of extended beam shifting, steering, and expanding, using a combination of theory and full numerical modelling, both for liquid crystal orientations and the transmitted light. Specifically, by exploiting three different function-specific and tunable birefringent nematic layers, we show an effective liquid-crystal beam control device, capable of precise control of outgoing light propagation, with possible application in projectors or automotive headlamps.
