متن کاملCoherent imaging at the diffraction limit
X-ray ptychography, a scanning coherent diffractive imaging technique, holds promise for imaging with dose-limited resolution and sensitivity. If the foreseen increase of coherent flux by orders of magnitude can be matched by additional technological and analytical advances, ptychography may approach imaging speeds familiar from full-field methods while retaining its inherently quantitative nat...
متن کاملCoherent Diffraction Imaging
For centuries, lens-based microscopy, such as light, phase-contrast, fluorescence, confocal and electron microscopy, has played an important role in the evolution of modern science and technology. In 1999, a novel form of microscopy, known as coherent diffraction imaging (CDI) or lensless imaging, was developed and transformed our traditional view of microscopy, in which the diffraction pattern...
متن کاملOn the Diffraction Limit for Lensless Imaging
Oakland, MD 21550 The diffraction limit for lensless imaging, defined as the sharpest possible point image obtainable with a pinhole aperture, is analyzed and compared to the corresponding limit for imaging with lenses by means of theoretical considerations and numerical computations using the FresnelLommel diffraction theory for circular apertures. The numerical result (u = p) obtained for the...
متن کاملCoherent soft X-ray diffraction imaging of coliphage PR772 at the Linac coherent light source
Single-particle diffraction from X-ray Free Electron Lasers offers the potential for molecular structure determination without the need for crystallization. In an effort to further develop the technique, we present a dataset of coherent soft X-ray diffraction images of Coliphage PR772 virus, collected at the Atomic Molecular Optics (AMO) beamline with pnCCD detectors in the LAMP instrument at t...
