Dual-view integral imaging 3D display based on a polarizer array

A dual-view integral imaging three-dimensional (3D) display based on a polarizer array is reported in this work. Two sorts of elemental images captured from two 3D scenes are alternated in the horizontal and vertical directions. Two sorts of polarizer units on the polarizer array, which are aligned to different elemental images, polarize the light rays emitting from those. Two 3D images are presented by two sorts of polarized light rays that pass through a pinhole array. Two 3D images with uniform voxels are provided in the central viewing direction. The observers wearing polarizer glasses 1 watch the 3D image 1, while the observers wearing polarizer glasses 2 watch the 3D image 2. The vertical viewing ranges of the reconstructed 3D images 1 and 2 are also enlarged.
