When holography meets coherent diffraction imaging.
The phase problem is inherent to crystallographic, astronomical and optical imaging where only the intensity of the scattered signal is detected and the phase information is lost and must somehow be recovered to reconstruct the object's structure. Modern imaging techniques at the molecular scale rely on utilizing novel coherent light sources like X-ray free electron lasers for the ultimate goal...
متن کاملGeneralised Holography Meets Coherent Diffractive Imaging
Coherent diffractive imaging (CDI) is an imaging technique that seeks to restore the exit-surface wave from intensity measurements, either in the far field diffraction plane or the Fresnel diffraction region. To date numerous strategies have been proposed to complete this restoration, the most successful being the original scheme proposed by Gerchberg and Saxton and its subsequent modifications...
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 کاملA scheme for lensless X-ray microscopy combining coherent diffraction imaging and differential corner holography.
We successfully use the corners of a common silicon nitride supporting window in lensless X-ray microscopy as extended references in differential holography to obtain a real space hologram of the illuminated object. Moreover, we combine this method with the iterative phasing techniques of coherent diffraction imaging to enhance the spatial resolution on the reconstructed object, and overcome th...
