A speckle pattern is a quasi-random interference pattern which typically emerges when
lasers are used as illumination sources in projection applications and which severely …

The free-space propagation of initially aberrated optical beams is considered with an
emphasis on aero-optical applications. An exact statistical solution of the paraxial wave …

We demonstrate a multimode-fiber bundle reference scheme in a photorefractive volume
hologram and discuss its angular/spatial selectivity both experimentally and theoretically …

Phase-shifting interferometry with a genetic algorithm is proposed. The correction of
unknown phase-shifting error is an important task in general phase-shifting interferometry …

Photo-thermo-refractive glass (PTR glass) is a multicomponent silicate glass doped with Ce^
3+, which changes its refractive index after exposure to UV radiation followed by thermal …

Les sols, couverture sédimentaire meuble en constante évolution puisque soumise aux
actions des agents de la pédogenèse, représentent le seul véritable enregistrement direct …

We investigated theoretically and experimentally angular directivity of a diffracted beam in
volume holographic gratings. We measured the angular direction of the diffracted beam as a …

The experimental study of the in-plain vibration of the speckle pattern in photorefractive GaP
and BTO crystals using the polarization self-modulation effect are presented. The simple …

The four-wave-mixing coherent optical oscillator is described, which is emitting light wave
with regular alternation of its phase between two discrete values zero and π. Such a periodic …

The notion of reflection strength S of a plane wave by an arbitrary non-absorbing layer is
introduced, so that the intensity of reflection is R= tanh2 S. We have shown that the total …
