Figure 4: Autostereoscopic 3D display.

(a) A schematic illustration showing the concept of an autostereoscopic display with the Lucius prism array. When the prism side of the Lucius prism array is placed on a mixed image in good alignment, two distinctively different images are seen by the left and right eyes. (b) Pictures taken from the positions of the left (SNU logo) and right eye (smiley face). (c) Transformation of the printed picture when the flexible Lucius prism sheet is bent backward (SNU logo) and forward (smiley face) while holding the left-hand side firm. The slit area was 4 cm×4 cm.
