过去的研究表明，三维物体场景可以转换为数字全息图。随后，可以从全息图的迭代盲截面图像重建（BSIR）的方法重建的目标场景。然而，计算是极其密集的，并且随着全息图的大小而升级。为了克服这个问题，我们提出了一种快速的BSIR方法，重建截面图像与少的焦点雾。虽然这里提出的技术是适用于一般的全息切片，我们使用的全息图获得的光学扫描全息作为例子，以显示该方法的有效性。
Past research has demonstrated that a three-dimensional object scene can be converted into a digital hologram. Subsequently, the object scene can be reconstructed from the hologram with an iterative blind sectional image reconstruction (BSIR) method. However, the computation is extremely intensive, and escalated with the size of holograms. To overcome this problem, we propose a fast BSIR method that reconstructs sectional images with less out-of-focus haze. While the technique proposed here is applicable in general to holography for sectioning, we use holograms acquired by optical scanning holography as examples to show the method's effectiveness.
