P‐8.12: One‐way Observable Floating Image Display for Aero Signage Using Micro Optical Prisms Which Enable to Make Transparent View from Back Side

Abstract

Suppose that you look Arabic numerals on transparent glass windows or in the air. Which does it mean ‘85’ or ‘28’? You end up watching the mirrored images when you view from back side. This paper shows a one‐way observable display for aero signage whose images are floating in the air. To solve mirrored image problems of an aero signage, the authors have utilized dye‐doped prisms and total internal reflection in optics. You know that water is generally clear and transparent but the water in a bath tub is little blue. The color changes depending on the depth of water. The deeper, the darker water becomes blue. This is the reason why some color is generated in the dye‐doped material. The authors put the letterings made by intaglio printings for arranging dye‐doped tiny prisms on a glass window. You can watch these colored letterforms from front and transparent pixels from back. Moreover the authors discuss a one‐way observable edgeilluminated window signage display which enables us to observe light emitting signs in the dark night without requiring external illuminating lights.

P‐8.9: Aero Signage Display Using Quasi‐Spatial Floating Image Generated by Holographic Optical Elements and Optical Illusion Object Maskings

“…To solve this problem, our laboratory had developed new optical gimmicks for unidirectional observable imaging using the dye-doped optical prisms. Since 2021, our research group has improved our proposed color generating mechanism using optical prisms and developed the manufacturing method of optical prisms by printing technology [2]. It is our motivation to realize the aero signage without mirrored image problem.…”
