We present an experimental setup useful for complex amplitude evaluation and phase
image quantification of three-dimensional (3-D) samples in digital holographic microscopy …

We present a new approach to obtain superresolved images in digital holography by means
of synthetic aperture generation using common-path interferometry and off-axis illumination …

We explore the polarization dependence of the nonlinear response of a planar nematic
liquid crystal cell doped with 1% wt of methyl red dye. The results obtained show that the …

Phase contrast imaging is performed for live biological species using photothermal induced
birefringence in dye doped liquid crystals. Using typical 4-f configuration, when liquid crystal …

A quantitative phase measuring technique is presented that estimates the object phase from
a series of phase shifted interferograms that are obtained in a common-path configuration …

In this work, we studied a newly reported class of colossal nonlinear effects observed near
the nematic-isotropic temperature transition. We show that the origin of this nonlinearity may …

Описан эффект самовизуализации прозрачных объектов и структур при фокусировке
пространствено-фазомодулированного лазерного пучка в протяженную …

Self-imaging of transparent objects and structures in focusing of a spatially phase-
modulated laser beam into an extended weakly absorbing medium is described. The laser …

Basic characteristics of the process of visualisation of transparent objects using the phase-
contrast method with a photothermal Zernike cell are analysed and evaluated. It is shown …

The lack of contrast represents a challenge in all imaging systems, including microscopy.
This manuscript proposes the use of an azobenzene liquid crystal material as a Zernike filter …
