A 3 D volumetric display system, which exploits persistence of vision by quickly scanning a 2 D display panel in rapid rotation so as to reconstruct 3 D images in a volume space, is presented in this paper. Voxel is defined as a graphic unit of information corresponding to one point in a 3 D image space, attributes of which such as the shape, position, total available number and density distribution always influence the perceived image quality and the overall system performance directly. Simulated modeling and quantitative analysis regarding the relationship of voxel attributes to the coupling between the size, the arrangement and refresh frequency of panel pixels are given in detail. In addition, experimental results show that original 3 D model usually has different perceived quality when positioned and oriented in different regions of the image space.
