Talbot and Talbot-Lau effects are frequently used in lensless imaging applications with light,
ultrasound, x-rays, atoms and molecules–generally in situations where refractive optical …

A linearization method with improved robustness for determining the displacement from sine
and cosine signals generated by optical encoders is presented. The proposed scheme is …

By means of experiment and simulation, we achieve unprecedented insights into the
formation of Talbot images to be observed in transmission for light diffracted at wavelength …

We theoretically predict and numerically simulate the discrete plasmonic Talbot effect in
dielectric graphene plasmonic waveguide (DGPW) arrays at THz wavelengths. The super …

An analysis of diffraction images in the deep Fresnel region produced by gratings with
random pit displacements around a nominal value is performed in this paper. Such pit …

Planar electromagnetic sources characterized by a periodic variation of their beam
coherence–polarization matrix are investigated, as far as the polarization features of the …

The combination of a grating as a periodic object and a Fresnel zone plate with a quasi-
periodic structure leads us to propose some novel array generator elements. It is shown that …
