Exact hidden-surface removal in digitally synthetic full-parallax holograms

摘要

A new algorithm for removing hidden surfaces from reconstruction of computer-generated holograms is presented.The object used in the algorithm is defined by surface model and each polygon composing the object provides amask for blocking the incident field into the backside of the polygon. The computational cost of the proposedalgorithm is 2 FFT/polygon by handling field transmission in Fourier space and integrating the surface diffractionmethod for generating fields. Reconstruction of a hologram synthesized by using the presented algorithm isdemonstrated.
