Computational methods have been established as cornerstones in optical imaging and
holography in recent years. Every year, the dependence of optical imaging and holography …

Rapid developments in synthetic aperture (SA) systems, which generate a larger aperture
with greater angular resolution than is inherently possible from the physical dimensions of a …

Holography provides access to the optical phase. The emerging compressive phase
retrieval approach can achieve in-line holographic imaging beyond the information-theoretic …

The race for miniature color cameras using flat meta-optics has rapidly developed the end-to-
end design framework using neural networks. Although a large body of work has shown the …

Empowered by pixel super-resolution (PSR) and phase retrieval techniques, lensless on-
chip microscopy opens up new possibilities for high-throughput biomedical imaging …

Wavefront sensing is the simultaneous measurement of the amplitude and phase of an
incoming optical field. Traditional wavefront sensors such as Shack-Hartmann wavefront …

Holography is a powerful technique that records the amplitude and phase of an optical field
simultaneously, enabling a variety of applications such as label-free biomedical analysis …

In this paper, we analyze a machine-learning-based non-iterative phase retrieval method.
Phase retrieval and its applications have been attractive research topics in optics and …

We propose a novel approach for lensless single-shot phase retrieval, which provides pixel
super-resolution phase imaging. The approach is based on a computational separation of …

We present a single-pixel imaging technique that enables phase extraction from objects by
complex Fourier spectrum sampling. The technique exploits a digital micromirror device to …
