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 a mask for blocking the incident field into the backside of the polygon. The computational cost of the proposed algorithm is 2 FFT/polygon by handling field transmission in Fourier space and integrating the surface diffraction method for generating fields. Reconstruction of a hologram synthesized by using the presented algorithm is demonstrated.
