Fig. 1. Sketched map for parallel acquisition of spatial spectrum: J*K hoxels Hjk(m,n) are imaged by M*N small lenses to form M*N images Imn(j,k) of the spatial spectrum.

Fig. 9. Pictures taken from multiple directions of the holographic display digital 3D models. Q1: Can you find out any differences between the 9 pictures? Q2: Can you imagine the 3D relations of each object only with the clues of such differences? It would be eye seeing in site for real 3D display.
