二维傅里叶变换相息图可以通过使用离散傅里叶变换来计算。离轴重建比轴上重建具有更低的重建误差。本文对傅立叶域中的相位量化效应作了新的分析。我们发现，相息图重建误差周期性地变化，根据所需的图像的位置时，一个大的虚拟区域被添加。利用迭代虚拟区域法和迭代隔行技术，模拟了量化相息图重建的误差对所需图像位置的依赖关系。
Two-dimensional Fourier transform kinoforms can be calculated by use of a discrete Fourier transform. It is well known that the off-axis reconstruction has lower reconstruction error than the on-axis one. Here we make what to our knowledge is a new analysis on the effect of phase quantization in the Fourier domain. We find that the kinoform reconstruction error changes periodically according to the position of the desired image when a large dummy area is added. The error dependence of quantized kinoform reconstruction is simulated on the position of the desired image by use of the iterative dummy area method and the iterative interlacing technique.
