Acceleration of hologram generation by optimizing the arrangement of wavefront recording planes

For a three-dimensional display using computer-generated holograms (CGHs), fast CGH calculations are required. The multiple wavefront recording planes (WRPs) method can reduce the computational amount by placing WRPs near an object. In previous studies using this method, the numbers and intervals of the WRPs were fixed. Hence, the calculation time was heavily affected by calculation conditions, such as variation in the distribution of object points. This paper proposes a method that can automatically optimize the number and arrangement of WRPs to accelerate CGH generation.
