在数字全息术中，成像过程由两种截然不同的技术组成：使用 CCD 相机的物理配准和使用专用软件的数字图像重建。为了获得最佳图像质量，除了衍射限制之外，记录参考光束和重建光束应该相同。全息图平面上参考场分布的测量可以以有限的精度完成。重建和记录参考光束之间差异的影响是本文的主题。给出了分析和实验结果。值得强调的是，上述差异也影响了数字全息干涉测量所获得的结果。
In digital holography the imaging process consists of two quite different techniques: physical registration using CCD camera and digital image reconstruction with specialized software. To receive the best image quality, besides diffraction limitations, the recording reference and reconstruction beams should be identical. The measurement of the reference field distribution at the hologram plane can be accomplished with a limited precision. The influence of differences between the reconstruction and recording reference beams is the subject of the paper. The analytical and experimental results are presented. It worth to emphasize that the differences mentioned influence results obtained in digital holographic interferometry as well.
