[Paper] Improving Aerial Image Continuity in Dual-Sided Display Using Periodic Motion of Slitted Retro-Reflectors

In this study, we propose a method for improving aerial image gaps in dual-sided aerial imaging optical system in AIRR by periodic motion of retro-reflector. Slitted retro-reflectors in the dual-sided display cause areas where no retro-reflectors exist in the image formation optical path, resulting in a problem of aerial image gaps. In this paper, as the gap position of retro-reflector can be continuously changed by periodically moving the retro-reflector, the visibility of the aerial image can be improved.
