||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.
