Title: | Mask-assisted deterministic phase-amplitude retrieval from a single far-field intensity diffraction pattern: Two experimental proofs of principle using visible light | Contributor(s): | Podorov, Sergey G (author); Bishop, Alexis I (author); Paganin, David M (author); Pavlov, Konstantin M (author) | Publication Date: | 2011 | DOI: | 10.1016/j.ultramic.2011.01.011 | Handle Link: | https://hdl.handle.net/1959.11/8291 | Abstract: | We recently developed a simple closed-form algorithm, which allows one to reconstruct the complex scalar wavefield at the exit surface of a sample, from the intensity of its far-field coherent diffraction pattern which is obtained in the presence of a suitable object-plane mask. In the first variant of this algorithm, the sample is contained within a uniformly illuminated sharp rectangular aperture in which at least one transverse dimension is at least twice that of the object. In the second variant, the sample is uniformly illuminated and is transversely displaced from an opaque rectangular mask in the object plane. For both variants, the far-field diffraction pattern is first Fourier transformed and then differentiated with respect to both transverse coordinates, in order to deterministically yield a series of independent reconstructions of the sample. Here we give an experimental demonstration of each of these two variants of our technique, using visible light. | Publication Type: | Journal Article | Source of Publication: | Ultramicroscopy, 111(7), p. 782-787 | Publisher: | Elsevier BV | Place of Publication: | Netherlands | ISSN: | 1879-2723 0304-3991 |
