Limited-angle optical diffraction tomography suffers from strong artifacts in tomographic reconstructions. Numerous algorithms, mainly based on regularization methods, have been developed recently to overcome this limitation. However, the quality of results still needs further improvement. Here I present a simple yet extremely effective method of increasing the reconstruction quality in limited angle optical diffraction tomography that can be combined with known tomographic algorithms. In the method a finite object support is generated from the object data and utilized in the reconstruction procedure as an additional strong regularizer. Practical aspects of this method are given together with examples of application.
有限角度光学衍射层析成像在层析重建中存在严重的伪影。最近已经开发了许多主要基于正则化方法的算法来克服这一限制。然而,结果的质量仍需进一步提高。在此,我提出一种简单但极其有效的方法,可提高有限角度光学衍射层析成像的重建质量,该方法可与已知的层析算法相结合。在该方法中,从物体数据生成有限的物体支撑,并在重建过程中用作额外的强正则化器。本文给出了该方法的实际应用方面以及应用示例。
