For any coding scheme designed for the synthesis of an optical wavefront by a computer-generated, amplitude-transmittance hologram, two types of synthetic holograms may be defined: the first is the encoded form of the optical wavefront itself; the second is the encoded form of the Fourier transform of the wavefront. The extent of the optical wavefront produced by the first type varies inversely, while that of the second type varies directly, with resolution. Five coding schemes are characterized by two important quantities: the first is the minimum number of samples that must be numerically evaluated and drawn; the second is the product of the minimum resolution (lines/unit length) and length (per dimension) required for the drawing. These quantities are a measure of the required computer and drawing device capabilities, respectively, and knowledge of them permits comparison of the coding schemes.
对于任何通过计算机生成的振幅透射率全息图来合成光波前的编码方案，可以定义两种类型的合成全息图：第一种是光波前本身的编码形式；第二种是波前傅里叶变换的编码形式。第一种类型产生的光波前范围与分辨率成反比，而第二种类型的光波前范围与分辨率成正比。五种编码方案由两个重要量来表征：第一个是必须进行数值评估和绘制的最小样本数；第二个是绘制所需的最小分辨率（线/单位长度）与长度（每个维度）的乘积。这些量分别衡量了所需的计算机和绘图设备的能力，了解它们有助于比较编码方案。
