Abstract
【解決手段】本発明の一実施形態では、印刷されたアレイが開示されており、磁気的に整列されたプレートレットの複数の同心リングが、フレネル構造、好ましくはフレネル反射器の形態で支持体上に配置される。有利には、磁界は、強度および方向に関して制御されることができるので、一般的なフレネル反射器に別に存在することがある球面収差を補償する磁界の設計を容易にすることができる。本発明の他の実施形態では、じょうご、ドーム、および円錐の光学的錯覚画像が印刷される。
【選択図】図3
Description
図1Aは、本発明の実施形態による議論の目的の「スイッチング」光学効果、または「フリップフロップ」と呼ばれる印刷された画像20の単純化された断面である。フリップフロップは、移行部25によって分離された、第1の印刷された部分22および第2の印刷された部分24を含む。インク展色材またはペイント展色材などの担体28によって囲まれた顔料フレーク26は、第1の部分内の第1の平面に平行に整列され、第2の部分内の顔料フレーク26’は、第2の平面に平行に整列される。フレークは、断面図において短い線で示される。フレークは、磁気フレーク、すなわち磁界を使用して整列されることができる顔料フレークである。それらは、残留磁化を保持しまたは保持しないことがある。各部分における全てのフレークが、互いにまたは整列のそれぞれの面に正確に平行ではないが、全体の作用が、本質的に示されるようなものである。図面は、同一のスケールではない。典型的なフレークは、幅が20ミクロンでありかつ厚みが1ミクロンであり得るので、図面は単に例示である。画像は、紙、プラスチック・フィルム、ラミネート、カード・ストック、または他の表面などの支持体29上に印刷されまたはペイントされる。議論に好都合のために、用語「印刷された」は、担体中の顔料を表面に塗布することを一般的に記載するために使用され、それは他の技術を含むことができ、「ペインティング」として呼ばれることがある他の技術を含む。
MgF2/Al/Ni/Al/MgF2の多層構造は、図39に示されるものと類似するポリエステル矩形格子の上部に真空蒸着される。格子の山および谷の幅は、7ミクロンである。山の高さは80nmである。材料は、エンボス加工された支持体から取り除かれ、24ミクロンの平均サイズを有するマイクロ・フレークに変換される。
