High-speed arbitrary pure phase hologram generation method based on a specific multi-phase

This paper presents a novel design method, to the best of our knowledge, for the creation of computer-generated holograms (CGHs) with arbitrary phases based on a specific multi-phase. This approach combines the design, production, and fabrication of holographic phase structures and requires only their assembly according to specific phase values. The arrangement of eight different specific phase values enables the production of 2D and 3D holograms comparable in quality to random phase holograms obtained through optimized Gerchberg–Saxton (GS) algorithms and requires only one-sixth of the computational time. The results of simulations and experiments indicate that this method provides a convenient approach to designing, processing, manufacturing, and reproducing high-quality phase holograms. It has the potential for widespread use in holography.
