摘要： A hyperchromatic three-dimensional (3D) imaging system creates multiple planar (2D) images located at different planes which are perceived by the observer's eyes as a 3D image, whereas a new functionality is added. Brightness of the display images is increased by applying narrow diffusion angles for the light scattered by the display. Narrow diffusion angle of the light also allows displays generating images such that each 2D image depends on the angle of observation, and a plurality of 2D images is perceived by the observer's eyes as a 3D image dependent on the angle of observation in a certain interval of the angles of observation. Angular spatial light modulator is employed as a display to generate beams directed in several predefined directions, beams being separately encoded for each direction. Scanning of an angle-maintaining diffuser screen by laser impinging onto the diffuser at different angles can be applied to ensure angle-resolved multi-view functionality.
