Scientists have advanced metasurface technology by developing a new design that simultaneously projects holographic images and creates special diffraction patterns with ten-fold rotation symmetry of ...

OAM detection of vortex beams using #-type lines is presented. In the far-field distribution of #-type line diffraction, the primary diffraction spots associated with the OAM of the beam can be easily ...

Researchers used the Poisson spot effect to create stable optical skyrmions with a laser and disc, simplifying studies for ...

Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

X-ray ptychography has emerged as a powerful imaging tool on X-ray synchrotron facilities. Implementation of ptychography on laboratory-scale X-ray sources has largely been hindered by their poor ...

A combined team of engineers from Jiangsu University and Harvard University used a non-destructive, light diffraction fingerprint technique to detect viral infections in cells. Their paper is ...
