Problems solved by technology

[0006] The purpose of the present invention is to address the existing domestic and foreign holographic printing systems where the output hologram is not a reproduction of a real three-dimensional object image; the requirements for shock resistance are high, the reconstructed stereo image has jumps and distortions, and the cost of the system is high The disadvantage is to provide a hologram output that can be used for holographic display of real three-dimensional objects; a computing holographic production and output system for hologram production and three-dimensional display without shock resistance and low system cost

Description

technical field [0001] The invention relates to a technology of hologram production and three-dimensional display, in particular to a calculation hologram production and output system. technical background [0002] Holographic three-dimensional display is one of the important application fields of laser holography technology. The general holographic display technology uses the coherent characteristics of lasers to record the three-dimensional information of three-dimensional objects to form a hologram, and uses the principle of diffraction to perform three-dimensional reconstruction. With the rapid development of computer technology and its peripheral equipment, holographic display technologies combined with computer systems continue to emerge. The synthetic holographic display system developed by Sony is a representative holographic production technology of optomechanical integration, but the practical application of holograms produced by computer simulation of optical pro...
