In this paper, geometric-phase lenses, which can not only correct wavefront aberrations but also magnify an aerial image, have been proposed for use in an aerial display system composed of a retroreflector array, an orthogonal-circular polarization grating, a right-angle prism, and a quarter-wave plate. The geometric-phase lenses were demonstrated both experimentally and computationally by arranging them in the aerial display configuration and observing aerial images. We also investigated the relationship between the magnification and the field of view of an aerial image, and it has been found that there is the trade-off relationship between them.
在本文中，提出了一种几何相位透镜，它不仅可以校正波前像差，还能放大空中图像，用于由后向反射器阵列、正交圆偏振光栅、直角棱镜和四分之一波片组成的空中显示系统。通过将几何相位透镜布置在空中显示配置中并观察空中图像，对其进行了实验和计算验证。我们还研究了空中图像的放大率与视场之间的关系，发现它们之间存在权衡关系。
