A "hierarchical hologram" and experiments using it are described. This type of hologram works both in optical far-fields and near-fields.We exploit the physical difference between the propagating light and optical near-field, where the former is associated with conventional holographic patterns obtained in optical far-fields, whereas the latter is associated with nanometric structure accessible only via optical near-fields. We also describe an experimental demonstration of the basic principles with our prototype optical elements.
描述了一种“分层全息图”及其使用的实验。这种类型的全息图在光学远场和近场都有效。我们利用传播光和光学近场之间的物理差异，其中前者与在光学远场中获得的传统全息图案相关，而后者与只能通过光学近场访问的纳米结构相关。我们还描述了使用我们的原型光学元件对基本原理的实验演示。
