发布时间：2018-08-16 09:22
【摘要】：为提高样品的重建精度及鲁棒性,提出一种可见光域上基于已知振幅信息约束的叠层成像方法。本方法仅需将待测样品周围的已知振幅图像作为先验参考信息,与样品共同叠层扫描,并代入迭代算法,即可获得优质的重建效果。通过模拟结果及搭建光学系统,对不同样品进行实验探究,证实了本方法的有效性。使用本方法,无需增加实验成本即可获取更优质的重建结果,并保持叠层成像技术的优势。本方法具有较强的抗噪声和抗孔径偏移能力,是一种简约、稳健、通用性强的衍射成像技术,具有较为重要的实用价值。
[Abstract]:In order to improve the reconstruction accuracy and robustness of the samples, a laminated imaging method based on known amplitude information constraints is proposed in the visible light domain. In this method, the image of known amplitude around the sample to be tested can be regarded as a priori reference information, and then superimposed with the sample and replaced by an iterative algorithm, a good reconstruction effect can be obtained. The effectiveness of this method is verified by the simulation results and the optical system. By using this method, better reconstruction results can be obtained without increasing the experimental cost, and the advantages of laminated imaging technology can be maintained. This method has strong anti-noise and anti-aperture migration ability, it is a simple, robust, universal diffraction imaging technology, and has important practical value.
