Abstract

Metasurface phase masks offer a new way of imaging in that the lens sizes are orders of magnitude smaller and allow for batch fabrication of a large number of miniature lenses. Unfortunately, current metasurface lens technology cannot simultaneously overcome the issues of image distortion for objects far from the optical axis and chromatic aberrations. Using simulations in Matlab, we study and design a single lens holographic system using metasurface lenses to drastically reduce both off-axis distortions and chromatic aberrations. Using a single metasurface lens, we demonstrate that a high quality image can be obtained for an object with a 30° angular diameter and 123 fractional bandwidth. We also experimentally demonstrate reduction of aberrations and 3D imaging for spare images as well as show mediocre quality reconstructed dense images.
