Abstract

A volumetric display system in which a plurality of modulated beams are projected onto a moving screen to generate an image in three dimensional space. In a first embodiment beams (6) from stationary beam sources (5) are projected onto a moving screen (1). In a second embodiment beam sources (5) are moved whilst screen (1) is moved. Screen (1) is preferably a helix which is rotated and beam sources (5) are preferably rotated about a common axis of rotation. In a third embodiment a screen (21) may be reciprocated whilst an array of beam sources (22) is rotated with respect to the screen (21).
