| Popis: | In this paper, we use a field lens and a holographic diffuser together to improve the printing efficiency of a holographic stereogram printing system based on the effective perspective images’ segmentation and mosaicking method. The light rays’ regulation function of the field lens and the modulation function of the holographic diffuser are analyzed. Holographic diffusers with different expanding angles are optimized by numerical simulations and verified by optical experiments. We can achieve a better holographic stereogram reconstruction effect as well as a better printing efficiency when adopting a field lens and a 10° holographic diffuser together. With the proposed method, the energy efficiency can be improved, and the printing time can be reduced greatly. |
