Abstract
A volumetric display system includes a display member which has a plurality of electrically-responsive optical shutters arranged in a layered relationship. The optical shutters include layers of a liquid crystal which preferably can be formed in geometric shapes which enhance the volumetric display. A projection system projects successive images onto the display member while successive ones of the optical shutters are switched into their translucent state. At any moment in time, all optical shutters except the successive one are maintained in a transparent state.
