An omnidirectional display that surrounds a viewer in all directions gives an immersive sensation by its wide field of view. Aerial imaging by retro-reflection (AIRR) has been proposed to form an aerial information screen with a wide viewing angle and has been utilized for an omnidirectional aerial display. We have conducted experiments to observe the behavior of medaka using our omnidirectional aerial display. In this case, medaka react to the aerial image. However, our omnidirectional aerial display has a small size and there is a problem that the small size may give stress on the medaka used for the experiments. In optomotor reaction experiments, it is required to show a cylindrical image to fish and there is no need to touch the stimulus image directly. In this situation, we can use a screen that surrounds a cylindrical water tank. This paper proposes an optics to realize omnidirectional display by use of a projector and a cone-shape mirror.
