Fractal zone plates (FZPs), i.e., zone plates with a fractal structure, are described. The focusing properties of this new type of zone plate are compared with those of conventional Fresnel zone plates. It is shown that the axial irradiance exhibited by the FZP has self-similarity properties that can be correlated to those of the diffracting aperture.
描述了分形波带片(FZP),即具有分形结构的波带片。将这种新型波带片的聚焦特性与传统菲涅耳波带片的聚焦特性进行了比较。结果表明,FZP所呈现的轴向辐照度具有自相似特性,这些特性可与衍射孔径的自相似特性相关联。
