The invention relates to the technical field of light sails, and particularly provides a light sail, a light sail regulation and control method and a light sail construction method. The light sail comprises a light sail body and a metasurface structure arranged on the surface of the light sail body in a partitioned mode, and the metasurface structure comprises a first metasurface structure, a second metasurface structure, a third metasurface structure and a fourth metasurface structure, the second metasurface structure is provided with a deflection phase for providing translation power for the optical sail body; and the first metasurface structure and the second metasurface structure are concentrically arranged. Left-hand circularly polarized light or/and right-hand circularly polarized light can be incident on the first metasurface structure or/and the second metasurface structure of the light sail, translation, rotation, overturning, pulling or self-stabilization movement of the light sail body is achieved, and the control flexibility of the light sail is improved.

    本申请涉及光帆技术领域,具体提供光帆、光帆调控方法以及光帆构建方法。该光帆包括光帆本体以及分区设置于光帆本体表面的超构表面结构,超构表面结构包括具有为所述光帆本体提供转矩或拉力的贝塞尔光束相位的第一超构表面结构,以及具有为所述光帆本体提供平移动力的偏折相位的第二超构表面结构;且第一超构表面结构与第二超构表面结构同心设置。可以通过在光帆的第一超构表面结构或/和第二超构表面结构入射左旋圆偏振光或/和右旋圆偏振光,实现光帆本体的平移、转动、翻转、拉动或自稳定运动,提高了对光帆的操控灵活度。
