We present a mathematical formalism to predict speckle-like interferometric out-of-focus patterns created by irregular scattering objects. We describe the objects by an ensemble of Dirac emitters. We show that it is not necessary to describe rigorous

In this paper we apply digital in-line holography to image opaque objects through a thick plano-concave pipe. Opaque fibers and opaque particles are considered}. Analytical expression of the intensity distribution in the CCD sensor plane is derived u

In this publication, the Luneberg integrals are revisited and the conditions of the using of such integrals have been recalled. Additivity law of Luneberg's integrals and the link with the Frenel kernel for the propagation are discussed. By means of

International audience; Interferometric out-of-focus imaging of ice particles is realized. A review of the recent developments performed to analyse the speckle-like out-of-focus images of rough particles is first proposed. A remaining challenge is th

International audience; Interferometric out-of-focus images of freezing droplets are presented, and compared to simultaneous in-focus images. In these experiments, the freezing process is characterized by a breaking of the initial droplet’s glare p

International audience; We propose to simulate holograms with the vectorial Rayleigh-Sommerfeld diffraction integral. This new approach is compared with a classical Fresnel diffraction integral, and that is done through the comparison of the kernels.
