3-D from a distance: a research team led by the author, Dohi Takeyoshi, and his colleague Hata Nobuhiko at the Graduate School of the University of Tokyo, has developed a technique for distant viewing of 3-D displays without the need for special glasses. The potential applications are exciting indeed.(New Technology)

CONVENTIONAL binocular stereoscopy has two major shortcomings. First, points can only be displayed as being relative to other points, and second, one's eyes become fatigued after viewing the image for 20 or so minutes. With Integral Photography (IP) for distant viewing, by contrast, a three-dimensional (3-D) image can be correctly projected into a 3-D space and viewed as though one were looking at real objects. The technology combines a two-dimensional microscopic convex lens array and super high-density pixel/super high-resolution display. Integral Photography for distant viewing is the ultimate three dimensional display method because many people can view a precise …
