摘要
En 中文
A method using a lens array to expand the viewing angle of holographic three-dimensional displays endows simplicity to optical systems and offers robustness against misalignment. In this study, we develop a method for generating holograms from point cloud data using the lens-array method. The proposed method utilizes the fact that the lens array generates a sparse light field in a checkered pattern to accelerate computation. Numerical verification and optical experiments show that the proposed method can generate holograms with wide viewing angles of 30 degrees degrees and 17 degrees degrees at high speeds.
