1. WO/2016/000001 DEVICE AND METHOD FOR MEASURING CIRCULAR DICHROISMWO07.01.2016
G01N 21/19
PCT/AM2014/000003MARGARYAN, Hakob MARGARYAN, Hakob
The invention is related to a device for measuring circular dichroism (CD) spectrum. The key element of the device of the current invention is the liquid crystal polarization diffraction grating (4). For CD measurement the difference in the absorption of left- and right-circularly polarized monochromatic light is used. A tunable monochromator (2) coupled to a wide spectral bandwidth light source, or other monochromatic or narrow spectral bandwidth light source is placed in front of the investigated sample (3) to provide CD measurements within the required spectral range. The signal with a high signal/noise ratio is detected using two single active-area photodetectors (5) placed at the output of the PDG, connected to downstream electronics (6) and digital processing system (7). CD measurements are achieved with the resolution of 3-5 millidegree or higher.

2. WO/2015/154105 DEVICE FOR NON-INVASIVE DETERMINATION OF GLUCOSE CONCENTRATION IN HUMAN ORGANISMWO15.10.2015
A61B 5/145
PCT/AM2014/000002MARGARYAN, Hakob MARGARYAN, Hakob
The invention refers to medical equipment, in particular, to optical device development for non-invasive determination of glucose concentration in human organism and it can be applied in medical equipment industry. A simple device for non-invasive determination of glucose concentration is offered, in which only the optical elements are used. The device registers the change of polarization vector of monochromatic light beam (4) reflected from the eye, and determined by the birefringence of eye, which is caused by the glucose content in eye fluid. Optical elements of new generation - liquid crystal polarization diffraction grating (6) and axial symmetric liquid crystal phase retarder (5) - are used in the proposed device, which lead to simplification of determination of rotation angle of polarization vector of monochromatic light beam and accuracy increasing. In addition, instead of linearly polarised light beam, usually used in such devices, the semiconductor laser beam with arbitrary polarization is used.

3. WO/2015/006788 THE METHOD FOR REGISTRATION OF CHANGES OF POLARIZATION STATE OF MONOCHROMATIC LIGHT RADIATIONWO22.01.2015
G01J 4/00
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.
