    • A varifocal lens includes a first phase plate including a plurality of first phase conversion elements having different sizes from each other, and a second phase plate including a plurality of second phase conversion elements having different sizes from each other, where the first phase plate and the second phase plate face each other along an optical axis and are movable relative to each other in a direction perpendicular to the optical axis to create displacement between the first phase plate and the second phase plate, and the plurality of first phase conversion elements and the plurality of second phase conversion elements are configured so that light transmitted through the first phase plate and the second phase plate is focused on different positions on the optical axis depending on the displacement between the first phase plate and the second phase plate.
    • 变焦距透镜包括具有彼此不同尺寸的多个第一相位变换元件的第一相位板和具有彼此具有不同尺寸的多个第二相位变换元件的第二相位板,其中第一相位板和 第二相位板沿着光轴彼此面对并且可在垂直于光轴的方向上相对于彼此移动以在第一相位板和第二相位板之间产生位移,并且多个第一相位变换元件和多个第一相位变换元件 第二相位变换元件被配置为使得透过第一相位板和第二相位板的光根据第一相位板和第二相位板之间的位移被聚焦在光轴上的不同位置上。
