摘要/Abstract

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: A visible light ptychography imaging method based on pre-known surrounding amplitude information is proposed,in order to effectively improve accuracy and robustness of the reconstruction.The method employs a known standard object as priori information which surrounds the sample.Ptychography scans the sample and the pre-known surrounding information,and then introduces them into the iterative algorithm.Finally a high quality reconstruction result is achieved after several iterations.With the simulations and by setting up the optical system,the experiments on different samples are carried out to further study its validity and versatility.In addition,the method shows a good anti-noise performance and anti-probe-offset capability.Due to the pre-known information constraint,a high quality reconstruction is completed without additional cost.The method also maintains the superiority of the traditional ptychography.This method is analyzed and proved to be simple-to-operate,steady,and versatile.The ptychography based on the pre-known information constraint has a quite promising practical value.

Key words: ptychography imaging, pre-known amplitude, coherent diffraction, iterative engine
