光学超颖表面是纳米散射体的二维阵列，其以亚波长空间分辨率修改光学波前。他们准备通过实现复杂的低成本系统来彻底改变光学，在这些系统中，多个超颖表面被光刻堆叠并与电子器件集成。对于成像应用，超表面堆栈可以执行复杂的图像校正，并且可以直接与图像传感器集成。在这里，我们证明了这个概念与一个微型平面相机集成的单片超表面透镜双校正单色像差，和图像传感器。双合透镜作为鱼眼摄影物镜，具有0.9的小f数，大于60° × 60°的视角，并且在850 nm波长下工作，具有70%的聚焦效率。该相机表现出几乎衍射极限的图像质量，这表明该技术在显微镜，摄影和计算机视觉光学系统开发中的潜力。 超颖表面具有用于成像系统的潜力，因为它们可以在亚波长空间分辨率下修改光学波前。在这里，Arbabi等人展示了针对单色像差校正的超表面透镜双合透镜，并将其与图像传感器集成以实现微型平面相机。
Optical metasurfaces are two-dimensional arrays of nano-scatterers that modify optical wavefronts at subwavelength spatial resolution. They are poised to revolutionize optics by enabling complex low-cost systems where multiple metasurfaces are lithographically stacked and integrated with electronics. For imaging applications, metasurface stacks can perform sophisticated image corrections and can be directly integrated with image sensors. Here we demonstrate this concept with a miniature flat camera integrating a monolithic metasurface lens doublet corrected for monochromatic aberrations, and an image sensor. The doublet lens, which acts as a fisheye photographic objective, has a small f-number of 0.9, an angle-of-view larger than 60° × 60°, and operates at 850 nm wavelength with 70% focusing efficiency. The camera exhibits nearly diffraction-limited image quality, which indicates the potential of this technology in the development of optical systems for microscopy, photography, and computer vision. Metasurfaces have the potential to be used in imaging systems since they can modify optical wavefronts at subwavelength spatial resolution. Here, Arbabi et al. demonstrate a metasurface lens doublet corrected for monochromatic aberrations, and integrate it with an image sensor to realize a miniature planar camera.
