摘要: The invention features a volumetric display system. A light beam representing an image is provided from a stationary source. A projection screen is rotated, relative to the stationary source, about a rotation axis. The light beam is projected onto the projection screen at a non-normal angle of incidence. The light beam is manipulated to reduce distortion in the image caused by projection of the light beam onto the projection screen.
