Paper Abstract
We propose an omnidirectional three-dimensional (3D) display system. This is a tool for communication around a 3D
image between a small number of people. This 3D display consists of multiple basic 3D display units. Each basic 3D
display unit consists of a projector and a curved HOE lens array sheets. The projector is located on the center of the
curvature of the curved HOE lens array, and it projects light rays on the curved HOE lens array with ascending vertical
angle 45-degree. Projected light rays are reflected and reconstruct the 3D image over the center of the curvature by the
curved HOE lens array. In this method, even though the viewing angle of each HOE lens does not increase, the viewing
angle of the 3D image by the curved HOE lens array can be increased. To verify the effectiveness of the proposed
method, we constructed the prototype basic 3D unit. The viewing angle of a 3D image was 44-degree. Therefore, the
viewing angle was increased by the proposed method compared to 17-degree by the conventional flat HOE lens array.
This paper describes the principle of proposed 3D display system, and also describes the experimental results.
