本文报道了一种快速、非迭代的纯相位全息图（以下简称PPOH）的制作方法。简言之，具有周期性相位图案的相位掩模被添加到源图像，并被转换成全息图。随后，仅保留相位分量作为纯相位全息图。实验结果表明，该方法所生成的PPOH重建图像的视觉质量良好，且优于现有方法所得到的图像质量上级。
A fast and non-iterative method for generating a phase-only hologram, hereafter referred to as the patterned-phase-only hologram (PPOH), is reported in this paper. Briefly, a phase mask with a periodic phase pattern is added to the source image, and converted into a hologram. Subsequently, only the phase component is retained as a phase-only hologram. Experimental evaluation reveals that the visual quality of the reconstructed images of the PPOH generated with our proposed method is favorable, and superior to that obtained with existing methods.
