This paper presents a novel 3D display using a new principle which has the features of both Integral Imaging (II) and volumetric display. The display we propose consists of two lens arrays, a convex lens array and a concave lens array, and one 2D display moving back and forth. The two lens arrays are placed between the 2D display and observer. The concave lens array forms elemental images, and the convex lens array and the formed elemental images reproduce a depth division image like the II method. When the observer watches the 2D display through the two lens arrays, he feels that the image displayed by the 2D display is reproduced not at the position of 2D display but at a certain depth according to the position of the 2D display. So when the 2D display is moved, the reproduced image also moves to another depth position. Therefore various depth images can be reproduced by the movement of the 2D display. This is how the proposed display reconstructs 3D space. This time we introduce the optics system which can reconstruct a wireframe cube by oscillating the 2D display only a few centimeters. We also show the result of simulation of the proposing display with a ray tracing method to confirm the moving parallax.

This paper presents a novel 3D display using a new principle which has the features of both Integral Imaging (II) and
volumetric display. The proposed display consists of one 2D display and two lens arrays, a convex lens array and a
concave lens array. The two lens arrays are placed between the 2D display and the observer. When the observer watches
the 2D display through the two lens arrays, he feels that the image displayed by 2D display is reproduced at the position
which is different from the position of the 2D display. Furthermore, by changing the position of the 2D display, the
image is reproduced at the different position than before. Therefore the various depth images are reproduced by moving
2D display. This is how the proposed display reconstructs 3D space. Here, we simulated this display with ray tracing and
checked its validity.
