ABSTRACT:
A three-dimensional display comprises a spatial light modulator (13), such as a liquid crystal display, sandwiched between first and second lenticular screens (12, 16). The pitch of the lenticules of the second screen (16) is an integral multiple of that of the first screen (12). The spatial light modulator (13) comprises a plurality of cells aligned with the lenticules of the first screen (12). A linear array of sequentially illuminated light sources (1-8) is focused by an optical system (10) into a plurality of collimated light beams with different angles of incidence on the first screen (12). For each illumination of the light sources, the spatial light modulator carries a plurality of 2D interlaced views.
