We have developed a tomographic diffractive microscope in reflection, which permits
observation of sample surfaces with an improved lateral resolution, compared to a …

We show experimentally that a resolution far beyond that of conventional far-field optical
profilometers can be reached with optical diffraction tomography. This result is obtained in …

In the present work, the Talbot effect of a square grating is analyzed when light is reflected
from a rough surface. It is shown theoretically that the scattered light intensity in the Fresnel …

Optical digital tomographic microscopy can be used for profilometry. The profile of the
surface can be estimated from measurements of the complex diffracted far field obtained …

An approach is introduced for the nonparametric reconstruction of the statistical properties of
penetrable, isotropic randomly rough surfaces from in-plane, co-polarized light scattering …

In this work we propose an efficient algorithm for reconstructing a one dimensional perfectly
conducting rough surface. The data are the complex amplitude of the diffracted far field in …

Identification of the defect type on substrate materials is essential for enhancing their yield
ratio. We propose a novel optical filter to discriminate between subwavelength-order …

In this work, we propose to extend an approach to calculate at any order (n), the functional
derivative of the scattered field with respect to the permittivity-contrast function of a three …

We deal with the problem of determining the profile of a perfectly conducting rough surface
from single-frequency and multistatic data. The two fundamental polarizations are …

Les équations de l'élastodynamique expriment une non linéarité entre les paramètres
mécaniques et le champ des déplacements. Cette non linéarité fait partie des difficultés …
