Virtual and augmented realities are rapidly developing technologies, but their large-scale penetration will require lightweight optical components with small aberrations. We demonstrate millimeter-scale diameter, high-NA, submicron-thin, metasurface-based lenses that achieve diffraction-limited achromatic focusing of the primary colors by exploiting constructive interference of light from multiple zones and dispersion engineering. To illustrate the potential of this approach, we demonstrate a virtual reality system based on a home-built fiber scanning near-eye display.
虚拟现实和增强现实是快速发展的技术，但它们的大规模普及需要具有小像差的轻质光学元件。我们展示了毫米级直径、高数值孔径、亚微米厚度、基于超表面的透镜，该透镜通过利用来自多个区域的光的相长干涉和色散工程实现了原色的衍射极限消色差聚焦。为了说明这种方法的潜力，我们展示了一个基于自制光纤扫描近眼显示器的虚拟现实系统。
