The fundamentals of digital recording and mathematical reconstruction of Fresnel holograms are described. The object is recorded in two different states, and the holograms are stored electronically with a charge-coupled-device detector. In the process of reconstruction the digitally sampled holograms are applied to the different coherent optical methods as hologram interferometry and shearography. If the holograms are superimposed and reconstructed jointly, a holographic interferogram results. If a shearing is introduced in the reconstruction process, a shearogram results. This means that the evaluation technique, e.g., hologram interferometry or shearography, can be influenced by numerical methods.
描述了菲涅耳全息图的数字记录和数学重建的基本原理。物体以两种不同状态进行记录，全息图通过电荷耦合器件探测器进行电子存储。在重建过程中，数字采样的全息图应用于不同的相干光学方法，如全息干涉术和剪切术。如果全息图叠加并联合重建，就会得到全息干涉图。如果在重建过程中引入剪切，就会得到剪切图。这意味着评估技术，例如全息干涉术或剪切术，可以受到数值方法的影响。
