Abstract

A meta-lens array-based Shack-Hartmann wavefront sensor has been developed to break the limits imposed by the size and curvature of traditional micro-lenses, which significantly improves both sampling density and angular resolution of phase measurement. Metasurface advances the field of optical phase measurement to smaller-scale complex wavefront characterization.

摘要

一种基于超透镜阵列的夏克-哈特曼波前传感器已被开发出来，以突破传统微透镜的尺寸和曲率所带来的限制，这显著提高了相位测量的采样密度和角分辨率。超表面将光学相位测量领域推进到更小尺度的复杂波前表征。
