最近，计算机生成的全息图的制造与纳米行程快速刀具伺服（nFTS）的金刚石端面车削已被证明。现有的金刚石旋转全息图的设计方法考虑到它们的螺旋形表面拓扑结构和只有波场的相位可以被调制的事实。在这里，我们提出了一种算法，使额外的考虑两个重要的制造相关的属性：所使用的金刚石工具的形状和有限的控制频率的nFTS。我们的方法是基于广义投影方法，并使设计的全息图在远场的任意强度分布的重建。实验结果表明，该方法的优点。
Recently, the fabrication of computer-generated holograms by diamond face turning with a nanometer-stroke fast tool servo (nFTS) has been demonstrated. Existing methods for the design of diamond-turned holograms account for their spiral-shaped surface topology and the fact that only the phase of a wave field can be modulated. Here we present an algorithm enabling the additional consideration of two important fabrication-related properties: the shape of the diamond tool used and the limited control frequency of the nFTS. Our method is based on the generalized projections method and enables the design of holograms for the reconstruction of arbitrary intensity distributions in the far field. Experimental results are presented, demonstrating the advantages of the method.
