ABSTRACT:
A method of effecting a three-dimensional print by a non-scanned exposure of three-dimensional lenticular print material is provided wherein a lenticular print material and a film having a plurality of exposed frames thereon are placed in opposing imaging planes and a lens and a periscope are positioned between the film and the print material; the periscope including first and second parallel mirrors positioned so as to reflect light along an optical path from the film through the lens to the print material, each of the parallel mirrors rotatable about a first axis normal to the lens optical axis and a second axis intersecting the first axis. Each of the frames is placed a predetermined linear distance from an optical axis of the lens to create a plurality of angular exposure zones corresponding respectively to the plurality of the frames and, for each of the plurality of angular exposure zones; the lens is placed in the center of the angular exposure zone; and the frame corresponding to the angular exposure zone is illuminated for delivering an image exposure of the frame to the periscope along the center of the angular exposure zone; thereby removing the translation (offset of) the image exposure delivered to the periscope from the lens along the center of the angular exposure zone from the periscope to the print material by rotating the periscope about the first axis and rotating the periscope about the second axis to restore the optical axis path to its original length.
