| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an imaging optical element that can provide an aerial image with excellent quality.SOLUTION: An imaging optical element comprises: a substrate 21 that has translucency; and partition walls 22 that are formed on the substrate 21 and each includes a plurality of openings 22a that are two-dimensionally partitioned. Each of the plurality of openings 22a has two reflection surfaces 22a1 formed to intersect with each other, and reflection films 23 are formed between the substrate 21 and partition walls 22.SELECTED DRAWING: Figure 8
【課題】優れた品質の空中画像を得ることができる結像光学素子を提供する。【解決手段】透光性を有する基板２１と、基板２１の上に形成され、二次元的に区画された複数の開口部２２ａを有する隔壁２２とを備え、複数の開口部２２ａの各々には、互いに交差する２つの反射面２２ａ１が形成され、基板２１と隔壁２２との間には、反射膜２３が形成されている。【選択図】図８ |
