Super-resolution Imaging of Limited-size Objects
Taeyong Chang, Giorgio Adamo, Nikolay I. Zheludev
Improvement of label-free far-field resolution of optical imaging is possible with prior knowledge of the object such as its sparsity or accumulated by a posteriori examination of…

Resolving Complex Subwavelength Grating Structures Using Topologically Structured Light
Thomas A. Grant, Eric Plum, Nikolay I. Zheludev +1
It has been seen recently that when probing a nanoscale object to determine, for example, size or position via light scattering, significant advantage in measurement precision can…

Localization of nanoscale objects with light singularities
Thomas A. Grant, Anton N. Vetlugin, Eric Plum +2
Unprecedented atomic-scale measurement resolution has recently been demonstrated in single-shot optical localization metrology based on deep-learning analyses of diffraction patter…
