Abstract

Buluş, bir yüzey üzerinde gözün ya da kameraların fark edemeyeceği şekiller oluşturulmasını ve oluşturulan bu şekilleri yüzey üzerine kaplanacak metal veya yarıiletken, düz ya da şekillendirilmiş ince filmler ile ortaya çıkarmasını sağlayan optik şifreleme yapısı ile ilgilidir. Buluş özellikle, Fabry-Perot, plazmonik veya güçlü girişim etkisini kullanan, bir yüzeye gizlenen bilginin ince soğurucu katman kaplı şeffaf bir alttaş ile ortaya çıkarılmasını sağlayan, arasında anahtar kilit uyumu bulunan şifreleme ve deşifreleme katmanına sahip optik şifreleme yapısı ile ilgilidir.
