Patent ID: 8011786

Claim:
A multi-perspective rear projection system for autostereoscopic reproduction of three-dimensional displays, including a rear projection wall ( 2 ), which has a first lenticular disk ( 8 ) on a back side ( 3 ) and a second lenticular disk ( 9 ) on a front side ( 4 ), and a picture generating unit ( 1 ), which is disposed behind the rear projection wall ( 2 ) and which has a plurality of projectors ( 7 a through 7 p ) for projecting each of a plurality of projected perspectives of the three-dimensional displays, characterized in that the rear projection wall ( 2 ) between the first lenticular disk ( 8 ) and the second lenticular disk ( 9 ) includes a third lenticular disk ( 10 ), and all three lenticular disks ( 8 , 9 , 10 ) have many cylindrical lenses extending in the same direction; that the rear projection wall ( 2 ), between the second and third lenticular disks ( 9 , 10 ), has a fourth lenticular disk ( 11 ) with cylindrical lenses, which are transverse to the cylindrical lenses of the other three lenticular disks ( 8 , 9 , 10 ); that the first and second lenticular disks ( 8 , 9 ) have the same number of cylindrical lenses, while the third lenticular disk ( 10 ) includes at least N times as many lenses as the first lenticular disk ( 8 ), where N is equal to the number of perspectives; and that the lenses ( 11 a ) of the fourth lenticular disk ( 11 ) have a lens width (pitch) that is equivalent to the lens width of the lenses ( 10 a ) of the third lenticular disk ( 10 ).
