Coherent diffraction imaging (CDI) is an alternative way to achieve high-performance
imaging without high-quality imaging lenses. Coherent modulation imaging (CMI) improves …

Co-phase error detection has been extensively studied as a key technology to achieve
diffraction-limited imaging for telescopes with segmented primary mirrors. This paper …

X-ray ptychography is a popular variant of coherent diffraction imaging that offers ultrahigh
resolution for extended samples. In x-ray ptychography instruments, the Fresnel zone-plate …

Ptychography is now integrated as a tool in mainstream microscopy allowing quantitative
and high-resolution imaging capabilities over a wide field of view. However, its ultimate …

We examine the interplay between spectral bandwidth and illumination curvature in
ptychography. By tailoring the divergence of the illumination, broader spectral bandwidths …

Computational techniques allow breaking the limits of traditional imaging methods, such as
time restrictions, resolution, and optics flaws. While simple computational methods can be …
