数字全息术是一种非常有效的物体三维成像工具，因为它直接产生相位信息而不需要额外的光学器件。另一个优点是数值聚焦，允许人们聚焦到任何期望的平面。它已被用于显微镜与高效率。数字全息显微术（DHM）的一个重要特征是它可以用于透明物体的相衬成像。这方面的DHM在这里被用来研究相位对象的动力学。将标量衍射理论的角谱传播方法用于全息图的数值再现。
Digital holography is a very effective tool for three-dimensional imaging of objects, since it yields the phase information directly without the need for additional optics. Another advantage is that of numerical focusing, allowing one to focus on to any desired plane. It has been used for microscopy with high effectiveness. One of the important features of digital holographic microscopy (DHM) is that it can be used for phase contrast imaging of otherwise transparent objects. This aspect of DHM is utilized here to study the dynamics of phase objects. Angular spectrum propagation (ASP) approach to scalar diffraction theory is used for numerical reconstruction of holograms.
