Abstract
A multi-view mask apparatus for creating a three-dimensional (3D) display. The apparatus includes a relay lens assembly that is non-inverting of images passed through the relay lens assembly including images of background objects. The apparatus includes a mask display device concurrently displaying first and second mask content via the relay lens assembly. The first mask content is viewable from a first point of view (POV) and the second mask content is viewable from a second POV or the first mask content is apparent from a first light source direction and the second mask content is apparent from a second light source direction. The relay lens assembly includes four lenticular sheets arranged into first and second pairs with adjacent back sides. The mask display device is disposed in one pair between two lenticular sheets and operated to display the first and second mask content as interlaced images under the lenticules.
