Quantitative phase imaging, integrated with artificial intelligence, allows for the rapid and
label-free investigation of the physiology and pathology of biological systems. This review …

Abstract In 1948, Dennis Gabor proposed the concept of holography, providing a pioneering
solution to a quantitative description of the optical wavefront. After 75 years of development …

When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

This Roadmap article on digital holography provides an overview of a vast array of research
activities in the field of digital holography. The paper consists of a series of 25 sections from …

Gallium nitride (GaN) light-emitting-diode (LED) technology has been the revolution in
modern lighting. In the last decade, a huge global market of efficient, long-lasting, and …

Lensless imaging provides opportunities to design imaging systems free from the constraints
imposed by traditional camera architectures. Due to advances in imaging hardware …

High-resolution optical microscopy has traditionally relied on high-magnification and high–
numerical aperture objective lenses. In contrast, lensless microscopy can provide high …

We demonstrate a versatile thin lensless camera with a designed phase-mask placed at sub-
2 mm from an imaging CMOS sensor. Using wave optics and phase retrieval methods, we …

The light microscope is traditionally an instrument of substantial size and expense. Its
miniaturized integration would enable many new applications based on mass-producible …

Point-of-care testing technique is increasingly important for healthcare management in
human being's daily life. However, traditional biosensor systems for health care are …
