    • A variable condenser for delivery of illumination, including a recursively nested circle-to-line fiber optic shape-converting cable and a focusable input lens system. At the input of the fiber optic cable, sets of individual optical fibers comprise successively smaller annuli recursively nested about a common center. At the output of the fiber optic cable, the sets of individual optical fibers comprise pairs of line segments recursively nested about the line midpoint, whereby the nesting level of the pairs of line segments has an exact or an approximate correspondence to the nesting level of the annuli. The output may be split into a plurality of lines, whereby the sets of individual optical fibers are distributed among the plurality of lines. The input lens system has a single adjustable focus means to vary the radius of an illumination spot incident upon the input of the fiber optic cable circle input.
    • 用于传输照明的可变电容器,包括递归嵌套的圆形到光纤形状转换电缆和可调焦输入透镜系统。 在光纤电缆的输入端,单独的光纤组包括相对较小的环,其相对于公共中心递归地嵌套。 在光纤电缆的输出处,各组光纤包括一对线段,其以线中点递归地嵌套,由此线段对的嵌套级别具有与嵌套级别的精确或近似对应关系 环带。 输出可以被分成多条线,由此各组光纤分布在多条线之间。 输入透镜系统具有单个可调节聚焦装置,以改变入射到光纤光缆圆输入端的照明点的半径。
