چکیده

It is commonly understood that the retrieval of a complex-valued object from its diffraction pattern using a support constraint is a difficult problem, the more so if the support is symmetric. In this Letter we show that, for just such a symmetric support, use of an iterative algorithm in which the basic iteration is specified by a difference map converges routinely. All that is required is sufficient oversampling in the diffraction pattern coupled with judicious choices of the parameters defining the difference map.

Lensless coherent imaging by a deterministic phase retrieval method with an aperture-array filter.

Recently we have proposed a noniterative and analytic phase retrieval method using the filter of an aperture array to reconstruct a complex-valued object from a diffraction intensity pattern [Phys. Rev. Lett.98, 223901 (2007)], but this method suffers from the restriction of the far-field condition of two distances between the object and the filter and between the filter and the detector for th...

Position-sensitive diffractive imaging in STEM by an automated chaining diffraction algorithm.

The diffractive imaging process used for retrieval of an aberration-free exit-wave function of a complex-valued object is optimized with a newly developed automated chaining diffraction (ACD) algorithm. Our algorithm enables automatic recovery of the amplitude and phase of the complex-valued objects with diffraction-limited resolution, starting from selected-area electron diffraction (SAED) pat...

Noniterative approach to the missing data problem in coherent diffraction imaging by phase retrieval.

When a very intense beam is used for illuminating an object in coherent x-ray diffraction imaging, the intensities at the center of the diffraction pattern for the object are cut off by a beam stop that is utilized to block the intense beam. Until now, only iterative phase-retrieval methods have been applied to object reconstruction from a single diffraction pattern with a deficiency of central...

Novel Fourier-domain constraint for fast phase retrieval in coherent diffraction imaging.

Coherent diffraction imaging (CDI) for visualizing objects at atomic resolution has been realized as a promising tool for imaging single molecules. Drawbacks of CDI are associated with the difficulty of the numerical phase retrieval from experimental diffraction patterns; a fact which stimulated search for better numerical methods and alternative experimental techniques. Common phase retrieval ...

Experimental verification of coherent diffractive imaging by a direct phase retrieval method with an aperture-array filter.

Recently, we have proposed a coherent diffractive imaging using a noniterative phase retrieval method with the filter of an aperture array. The first (to our knowledge) experimental demonstration of this coherent imaging is presented here, in which a complex-valued object illuminated by a diode laser is reconstructed from the isolated diffraction intensities of the object's wave field, transmit...
