Lateral and axial resolution criteria in incoherent and coherent optics and holography, near- and far-field regimes [PDF]
, 2019 This work presents an overview of the spatial resolution criteria in classical optics, digital optics and holography. Although the classical Abbe and Rayleigh resolution criteria have been thoroughly discussed in the literature, there are still several ...

Quantum coherence generated by interference-induced state selectiveness
, 2001 The relations between quantum coherence and quantum interference are discussed. A general method for generation of quantum coherence through interference-induced state selection is introduced and then applied to `simple' atomic systems under two-photon ...

Surface characterization in fabrication environments using angle resolved light scattering: From roughness and defect analysis to in-situ coating inspection [PDF]
EPJ Web of ConferencesThe performance of an optical component or surface might quicky be limited by light scattering induced by the surface and coating roughness, as well as imperfections and contaminations. On the other hand, the scattered light contains valuable information
