A new optical architecture of multiview projection displays, based on mirrored light tunnel is presented. According to current concept, all perspective images should be arranged in line on the same projection panel. The light tunnel is made of two or more parallel plane mirrors, installed between the image projector and the screen. The mirrors are installed horizontally, close to the screen, being perpendicular to its surface. One of the perspective images is projected directly to the screen while the others experience reflection before they strike the screen. Vertical arrangement of the viewing zones is changed to horizontal with a help of slanted directional diffuser, incorporated in directional screen. The important features of new architecture is the usage of single projection lens and the absence of keystone distortion of projected perspective images.
