[Paper] Acceptable Arrangement of Multiple Retro-reflectors with a Gap to Visually Complement the Gap of Aerial Image in AIRR

For realize large aerial imaging by retro-reflection (AIRR) with reduced effect of retro-reflectors gap, we propose a method to visually complement the gap of aerial image. AIRR composed of multiple retro-reflectors for large image size has a problem of the gap in the aerial image due to the reflector gap. In this paper, we derive equations for obtaining the width of the gap between retro-reflectors and the width of the retro-reflectors that enable the perception of the entire aerial image. The equation provides the maximum width of the retro-reflector that can complement the gap depends on the viewing distance and distance from the eye to the retro-reflectors.
