Abstract :
Experimental results of a volumetric display system based on three-dimensional (3D) scanning using an inclined image are reported. An optical real image of an inclined two-dimensional (2D) display device is moved laterally by an optical mirror scanner. Inclined cross-sectional images of a 3D object are projected in accordance with the position of the image plane. A 3D real image is formed as a stack of 2D cross-sectional images as a result of high-speed scanning. This 3D image can satisfy all the criteria for stereoscopic vision. An experimental system using a galvanometer mirror and a digital micromirror device was constructed, and generated three-dimensional images consisting of 1024×768×200 voxels. A multilevel image can be formed by a spatial dithering technique, even though the binary display device was used.
