The determination of the complex amplitude in the hologram is one major step in the realization of computer generated holograms. Usually the input distribution is assumed to be in a plane parallel to the hologram plane. However, sometimes a more flexible geometry is of interest. Here, in particular an arbitrarily shaped computer generated hologram of a plane input distribution is considered. The calculation of the complex amplitude in the hologram mainly consists of a Fourier transformation and a nonlinear coordinate transformation. The feasibility of this procedure is demonstrated by optical reconstructions of cylindrically shaped computer generated holograms in arbitrarily oriented planes.
确定全息图中的复振幅是实现计算机生成全息图的一个主要步骤。通常假设输入分布在与全息图平面平行的平面内。然而，有时更灵活的几何结构会引起人们的兴趣。在此，特别考虑平面输入分布的任意形状的计算机生成全息图。全息图中复振幅的计算主要包括傅里叶变换和非线性坐标变换。通过对任意取向平面内圆柱形计算机生成全息图的光学重建，证明了该方法的可行性。
