Metasurfaces with compact footprint and large information capacity bring unprecedented possibilities for the miniaturized optoelectronic systems. With the further exploration of intriguing wavefront tailoring possibilities, multiple dimensional multiplexing and dynamic modulation techniques combined with metasurface designs gradually become crucial research trends. Here, we utilize resonance effects and geometric phase of metasurfaces to simultaneously shape the amplitude, phase and polarization of light, and rebuild a vectorial holography with customized patterns and polarizations. By selecting the desired polarization combination continuously, dynamic display of vectorial meta-holography with 4-fold degeneracy is demonstrated. Such a method can precisely modulate the spatial phase and polarization distributions simultaneously at each frame, while the dynamic tunability is easy to implement based on polarization rotation. Such versatile and compact metasurfaces may provide promising solutions to dynamic and near-eye display, compact LiDAR, optical encryption, and date storage.

基于超表面的全斯托克斯矢量全息动态显示

具有紧凑占地面积和大信息容量的超表面为小型化光电系统带来了前所未有的可能性。随着对有趣的波前裁剪可能性的进一步探索，多维复用和动态调制技术与超表面设计相结合逐渐成为重要的研究趋势。在这里，我们利用超表面的共振效应和几何相位同时塑造光的振幅、相位和偏振，并重建具有定制图案和偏振的矢量全息。通过连续选择所需的偏振组合，演示了具有 4 倍简并性的矢量元全息动态显示。这种方法可以在每一帧同时精确地调制空间相位和偏振分布，而基于偏振旋转的动态可调性很容易实现。这种多功能且紧凑的超表面可为动态和近眼显示、紧凑型 LiDAR、光学加密和数据存储提供有前景的解决方案。
