Paper Abstract

Previously, the author has described a new 3D imaging technology entitled 'real depth' with several different configurations and methods of implantation. Included were several methods to 'float' images in free space. Viewers can pass their hands through the image or appear to hold it in their hands. Most implementations provide an angle of view of approximately 45 degrees. The technology produces images at different depths from any display, such as CRT and LCD, for television, computer, projection, and other formats. Unlike stereoscopic 3D imaging, no glasses, headgear or other viewing aids are used. In addition to providing traditional depth cues, such as perspective and background images occlusion, the technology also provides both horizontal and vertical binocular parallax producing visual accommodation and convergence which coincide. Consequently, viewing these images do not produce headaches, fatigue, or eyestrain, regardless of how long they are viewed. A method was also proposed to provide a floating image display system with a wide angle of view. Implementation of this design proved problematic, producing various image distortions. In this paper the author discloses new methods to produce aerial images with a wide angel of view and improved image quality.
