The most commonly used configurations in digital holography-namely Fourier holograms, Fresnel holograms, and image-plane holograms-are analyzed with respect to Seidel's wave aberration theory. This analysis is performed by taking into account the phase terms involved in the recording and reconstruction processes. The combined phase term from both processes is compared with the Gaussian-reference sphere, from which the wave aberration terms can be obtained. In conjunction with the analysis, for each of the aberration terms, conditions can be set to eliminate them. Wave aberrations are plotted to show how strongly different setups are affected.
针对数字全息术中最常用的配置，即傅里叶全息图、菲涅耳全息图和像面全息图，依据赛德尔波像差理论进行了分析。该分析通过考虑记录和重建过程中涉及的相位项来进行。将这两个过程的组合相位项与高斯参考球面进行比较，由此可得到波像差项。结合该分析，对于每个像差项，可以设定条件来消除它们。绘制波像差图以展示不同设置受影响的程度。
