For decades, imaging weakly scattering phase objects, such as cells, has been an active area of research across various fields, including biomedical sciences. One common approach uses chemical stains ...

BCDI uses wideband illumination to improve photon efficiency across the full spectrum, eliminating the need for coherent light. However, this extension introduces diffraction aliasing and significant ...

Optical computing has emerged as a powerful approach for high-speed and energy-efficient information processing. Diffractive ...

(Nanowerk News) In 1999, UCLA professor John Miao pioneered a technique called coherent diffractive imaging, or CDI, which allows scientists to re-create the 3D structure of noncrystalline samples or ...

Thanks to a set of unique properties, diffractive optical elements have the potential to transform light into almost any desired distribution. Joshika Akhil gives the low-down on the technology that ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...

Now you see it: A schematic of the experiment, in which an optical diffractive camera hides information by concealing it within ordinary-looking “dummy” patterns. (Courtesy: A Ozcan) Information ...

The schematic of the presented QPI diffractive network, which reveals the quantitative phase information of an object behind a random unknown diffuser without the need for a digital image ...
