||PCT/AM2015/000001||MARGARYAN, Hakob||MARGARYAN, Hakob|
Invention relates to development of centrally symmetric liquid crystal polarization diffraction waveplate (LC CDW) and its fabrication method. In the created optical element the ordering of LC molecules directors along each radius corresponds to axial LC polarization diffraction grating (PDG), and in two PDGs recorded along one diameter, the ordering of LC directors is symmetric regarding the center. Recording is based on illumination of substrate coated by photo-orienting material and is realized by overlapping of two - left and right circularly polarized beams through optical gap with angular sector shape, the peak of which coincides with the center of circular substrate. When illuminating by linearly polarized beam at the output of centrally symmetric LC CDW only in +/-1 diffraction orders the centrally symmetric diffracted beams in the shape of inscribed circle, corresponding to left and right circularly polarized components, are observed.

||PCT/AM2013/000005||"YEREVAN STATE UNIVERSITY" STATE NON-COMMERCIAL ORGANIZATION||MARGARYAN, Hakob|
The invention refers to optics, in particular to the development of a new method for optical measurements. Possible fields of the invention application are: polarimetry, spectropolarimetry and ellipsometry. The invention proposes a method for registration of changes in monochromatic light beam polarization, based on using an axial symmetric liquid crystal phase retarder and a polarization diffraction grating. The radial symmetric phase retarder allows to create a unique correspondence between the state of incident beam polarization vector and the intensity distribution of the radial symmetric beam passed through the polarization diffraction grating placed after the retarder. In the proposed method for registration of changes in a monochromatic light beam polarization the state of polarization vector is determined by values of Stokes' parameters, obtained by a single measurement.
