We have performed cuts of the reconstructed images signal |E n (x, y| 2 obtained for different sideband orders n along the horizontal line y = 174 (this value has been chosen because

To discuss on noise in digital digital holography, we will consider both the case of off-axis holography, where the hologram is obtained from one frame of the CCD camera, and the

Compared to digital Fresnel holography, this element is a critical point that influences several aspects of the reconstruction process: filtering/algorithms, aperture,

This paper presents a comparison of image denoising al- gorithms applied to the processing of phase data images degraded with speckle noise in the context of digital holog-

Les deux méthodes de détermination de l’HR d’un granulé présente une variabilité propre à chacune qu’il est nécessaire d’étudier pour pouvoir la prendre en compte

Inserted in the reference arm of the interferometer, the Wollaston prism allows generating two orthogonally crossed waves and analyzing shocks waves whatever

In this work we proposed a replicable method for policy analytics aimed to determine inhabitants’ val- ues of space: values that individuals give to different territorial
