Abstract
A system and method for creating a three-dimensional (“3D”) volumetric display using a linear array of active point light sources and projecting those points on a mirrored surface. The linear image is then modulated and swept along that mirrored surface to create a two-dimensional (“2D”) raster image. Simultaneously, the mirrored surface upon which the raster image is created is rotated along a axis that is orthogonal to the raster image. During the orthogonal rotation the 2D raster image is redrawn as separate frames in a timed and coordinated manner such that each pixel element (“pixel”) of the 2D image is displayed sequentially in 3D space as a volumetric pixel element (“voxel”). The integrating characteristics of human sight are then used to create the impression of a volumetric surface from the integration of the raster images.
