Abstract

We will demonstrate the construction of an optical device that can interchange the left and right scenes. This device is based on a periscope architecture in which the left scene is double-reflected to the right eye and vice versa. It is widely known that the interchange between the left and right scenes of a stereogram causes the perception of a concave object as a convex one and vice versa. Therefore, when the constructed device is used to look at a real symmetric concave object, we see the reversed convex object. This device demonstrates three-dimensional perception and the free-space interconnectivity of optics; i.e., the left and right scenes cross each other without change when they are interconnected to the right and left eyes, respectively.
