Title:
METALENS ARRAY, AND WAVEFRONT DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/125542
Kind Code:
A1
Abstract:
A metalens array and a wavefront detection system, wherein the metalens array comprises at least one meta-array unit; the meta-array unit comprises a plurality of transmission metalenses (1, 2, 3) having different working wavelengths; and the plurality of transmission metalenses (1, 2, 3) have the same focal length and are used for focusing light that has different wavelengths in incident light to different positions on a first plane. The plurality of transmission metalenses (1, 2, 3) having different working wavelengths can focus the light that has different wavelengths to different positions of a focal plane, such that focal shifts of different wavelengths are obtained, and thus wavefronts of a plurality of wavelengths can be calculated.
