Double-layer metasurface coma aberration elimination imaging lens suitable for unmanned aerial vehicle mobile shooting

The invention discloses a double-layer metasurface coma aberration elimination imaging lens suitable for unmanned aerial vehicle mobile shooting. The lens comprises a doublet lens, and the doublet lens comprises first glass serving as a lens substrate, and a first micro-nano amorphous silicon cylindrical structure layer and a second micro-nano amorphous silicon cylindrical structure layer which are arranged on the upper surface and the lower surface of the glass respectively and are used for converging light. According to the invention, the doublet lens with the micro-nano amorphous silicon cylindrical arrays on both sides is used, so that the coma aberration condition of the curved lens is improved. The lens with the micro-nano structure is used for improving the imaging efficiency, the size and weight of the lens are reduced as much as possible, and the burden of the system on the unmanned aerial vehicle is fully reduced. 本发明公开了一种适用于无人机移动拍摄的双层超表面消彗差成像镜头，所述镜头包括双合透镜，该双合透镜包括作为透镜基底的第一玻璃，分别设置于该玻璃上、下表面的用于会聚光的第一微纳
