英文摘要 | In this paper, ptychographic phase microscopy (PPM) with digital illumination addressing via a digital micromirror device (DMD) was demonstrated. A moving circular pattern is sequentially lighted up by a DMD and projected on the sample for illumination stepping, and a CCD camera records the generated diffraction patterns. Then, the quantitative phase distribution of the sample can be reconstructed from the diffraction patterns by using an iterative algorithm. Compared with conventional PPM approaches, this method has a fundamentally enhanced imaging speed due to the usage of the digital scan to replace the conventional mechanical scan. Furthermore, parallelized illumination strategy, which loads multiple pupils to DMD simultaneously, is used to further improve the imaging speed to 0.8 s per phase image. We envisage that this method will contribute to high-contrast, quantitative phase imaging of transparent samples without labeling. © 2021 Elsevier B.V. |
