23-6 再帰反射によるLED 空中像(AIRR)の視域 : 再帰反射シートの角度とLED 空中像の輝度の関係(第23部門 立体映像技術)

We have proposed Aerial Imaging by Retro-Reflection (AIRR). To investigate the viewing angle difference between the retroreflective elements, we measure the luminance distributions of an aerial image along the rotation angle of retroreflective sheeting. The micro-beads type forms the aerial image in significantly wider ranges than the prism type.
