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 ...

A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography. In recent years, the scientific ...

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

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 ...

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