Expansion of Displaying Volume in Projection Type Electro-holography

Abstract

In the holographic 3D display using mist screen, large 3D images can be observed with wide viewing angle. However, in the previous methods, it was difficult to observe the sides of the projected 3D images. In this paper, we studied a process to expand the displaying volume of the projected 3D images by preparing a jetting system improving the characteristics of the mist screen and by combining the reconstructing waves reflected from two SLM's. As this result, by adopting our system, 3D images are seen to become observable with wider viewing angle including sides than before.
