Spatial coherence of fields from generalized sources in the Fresnel regime
Andre Beckus, Alexandru Tamasan, Aristide Dogariu +2
Analytic expressions of the spatial coherence of partially coherent fields propagating in the Fresnel regime in all but the simplest of scenarios are largely lacking and calculatio…
Incoherent lensless imaging via coherency back-propagation
Ahmed El-Halawany, Andre Beckus, H. Esat Kondakci +4
The two-point complex coherence function constitutes a complete representation for scalar quasi-monochromatic optical fields. Exploiting dynamically reconfigurable slits implemente…
Coherence measurements of scattered incoherent light for lensless identification of an object's location and size
H. Esat Kondakci, Andre Beckus, Ahmed El Halawany +3
In absence of a lens to form an image, incoherent or partially coherent light scattering off an obstructive or reflective object forms a broad intensity distribution in the far fie…
