Holographic 3D display system using holographic optical element
In recent years, the study of 3D-display is rapid development and many researchers propose many methods. Holography is best method. But, it is difficult that we developed holographic movie in the future tense. At the present time, stereogram method will make practicable in the near future. These methods can easily make animated 3D image. But this method has one problem; this method is conflict between convergence and accommodation. An observer can't watch 3D-display of this method long time. The authors will solve this problem. The authors proposed the 3D-display system that is used holography and stereogram technology. The proposed system has little conflict between convergence and accommodation. The authors developed this 3D-display system. The developed system has four focuses in horizontal direction. The display parts of the developed system are LCD display because the developed system can play 3D movie. Of cause, this display doesn't have special glasses. But, color of this display is single color. It is red. The authors will develop full color 3D-display. The picture size of this display is about 6 inch and the form of this display is very large. The author will develop small size system and show large size picture.
