Abstract (en)

[origin: WO9938335A1] Three-dimensional imagery based on a series of two-dimensional images is produced and displayed. A frame (20) housing a series of image displays (22) displaced at differing radial distances from the center (39) of the frame is rotated at 60 hertz or greater. As each display rotates past the viewer, a different sectional slice of a three-dimensional image is displayed. Thus, a full rotation of the frame provides the viewer with a full view of the three-dimensional object. The high rotational speed of the system visually merges the slices and the radial displacement of the displays provides depth to the image. This combination results in the presentation of a true three-dimensional image without the need for viewing aids. Additionally, multiple viewers can view the same or differing three-dimensional images.
