In previous research, we can see through the rear seat which is covered with retro-reflective material as a screen and recognize directly backward of a car. In this paper, we propose a projection optical system for binocular vision by using the stepwise lens array and field lens. We conducted an experiment to verify the visibility of the proposed system.I.3.7 [Three Dimensional Graphics and Realism]Virtual reality
