P-87: Optimization of Display Image in Fresnel Lens-based Floating Display System Using a Curved Screen

As an approach for a 3D real image display system without special glasses, a Fresnel lens-based 3D rear-projection display system is implemented. In this display system, the conventional 2D video image is projected into the air through some projection optics, a screen and a pair of Fresnel lens. As a result, it can form a floating video image having a real depth. In this paper we suggest the method to compensate the image distortion in floating display system. and we have measured the image depth and viewing angle of floating image about the various type of Fresnel lens array in floating display system using curved screen.
