Abstract:
1. A holographic three-dimensional (3D) display system, comprising a photographing and capturing device of color real-time holographic 3D image information, a projective restoration device of real-time holographic image information, and a holographic functional screen, wherein the photographing and capturing device comprises M×N color 2D image capturing units C the projective restoration device comprises M×N color 2D image projection units P M, N, m, and n are natural numbers, and at least one of M and N is greater than 2; the holographic functional screen has regularly distributed fine spatial structures, which distribution makes an input light beam that has reached the holographic functional screen in any direction to have a corresponding spectrum spatial stretching output, wherein a spatial stretching angle of an output light beam is the spatial sampling angle ω
