摘要：

Novel method for synthesizing light waves from objects expressed in surface model is presented for fast creation of digitally synthetic holograms. This method has a feature of coordinates rotation in Fourier domain, in which only twice FFTs and an interpolation of spectrum are necessary for calculation of light waves from each object's plane. Therefore, presented method is rather faster than conventional ray-tracing when large scale full-parallax holograms are synthesized in a surface model. Phases of a surface object are also discussed in relation to controlling the direction and diffusiveness of object waves. Furthermore, fabrication of a hologram based on the method and its reconstruction are presented for a demonstration.
