论文摘要
在许多方面，变焦金属双重运动表在传统变焦镜头上具有前所未有的优势，例如超紧凑型，CMOS兼容性和小型化。但是，由于色差，大多数人只能在狭窄的频段中起作用。在这里，我们在数字上展示了受Moiré镜头原理启发的宽带宽带Zoom Metalens Doublet。通过全球优化可见光中金属双重曲线的多波长相曲线来实现这种设计。双重运动员可以在440 nm，540 nm和640 nm的波长下实现可观的连续1-10个缩放范围，具有高度高达86.5％的高度对焦效率和极化不敏感的效率。
Zoom metalens doublet exhibits unprecedented advantages over the traditional zoom lens in many aspects, like ultra-compactness, CMOS compatibility, and miniaturization. However, most of them can only work in a narrow band due to chromatic aberration. Here, we numerically demonstrate a broadband achromatic zoom metalens doublet inspired by the Moiré lens principle. This design is achieved by globally optimizing the multi-wavelength phase profiles of the metalens doublet in the visible. The doublet can achieve achromatic continuous 1-10 zoom range at wavelengths of 440 nm, 540 nm, and 640 nm, featuring high focusing efficiency up to 86.5% and polarization insensitivity.
