Keywords:projector, pupil, omnidirectional display

We have proposed a method to form an omnidirectional aerial image using a beam splitter has a cone-shaped by the aerial imaging method AIRR (Aerial Imaging by Retro Reflection) by retroreflection. In addition, we have proposed a method to display a wide range of images with a projector because our proposed optical system is compact. However, this method cannot see the image without the screen. Therefore, we propose a method to project the image of the projector in all directions without a screen.
