Abstract :
A new experimental volumetric display system based on inclined-image scanning is reported. A volumetric image is formed as a stack of about one hundred cross-sectional images. A high-speed video interface apparatus for controlling a digital micromirror device, which displays the cross-sectional images, is introduced to achieve real-time updating of volumetric images. The cross-sectional images of a three-dimensional (3D) object are generated from a depth map of the 3D polygon surface model within a video frame rate. In addition, to increase the viewing angle, the numerical aperture of an optical system is in-creased by use of a larger scanner mirror.
