  • The Anisotropy of Light Propagation in Biological Tissues 
    ACHIMOVA, E.; ABASHKIN, V.; CAZAC, V.; PRISACAR, A.; MASHALKIN, A.; LOSMANSCHII, C. (Universitatea Tehnică a Moldovei, 2021)
    In this paper we present a modified transmission digital holographic microscope that can be used to image the state of polarization of biological tissue. The resulting device, called polarization-sensitive phase-shifting ...
  • Application of diffraction gratings for phase imaging enhancement in digital holographic microscopy 
    MESHALKIN, A.; CAZAC, V.; ACHIMOVA, E.; ABASHKIN, V.; SHEVKUNOV, I.; KATKOVNIK, V. (Tehnica UTM, 2016)
    In this work we simulated the application of phase diffraction grating for phase imaging enhancement of a phase object reconstruction. At first, the phase retrieval of object was modeled without the use of mask and then ...
  • Design of the Holographic Fiber-optic Electronic Speckle Pattern Interferometer for Optical Constants of Glasses Measurements 
    IASENIUC, O.; ANDRIESH, A.; ACHIMOVA, E.; ABASHKIN, V. (Technical University of Moldova, 2011)
    An elaboration the holographic fiber-optic electronic speckle pattern interferometer (ESPI) which can will be apply for measurement of the optical constants is described. This interferometer with CCD Smart Camera can be ...
  • Direct relief formation during holographic recording in nanomultilayers As2S3/Se 
    TRIDUH, G.; PRISACAR, A.; MESHALKIN, A.; ABASHKIN, V.; ACHIMOVA, E.; ENAKI, M. (Academia de Ştiinţe a Moldovei, 2014)
    The process of obtaining of high-efficiency relief holographic gratings includes laser irradiation and chemical etching of photosensitive film in a special selective solution. This process can be greatly enhanced by the ...
  • Nanomultilayer As2S3:Mn-Se Systems: Properties and Use as the Recording Media 
    PAIUK, O.; MESHALKIN, A.; TRIDUH, G.; PRISACAR, A.; ACHIMOVA, E.; STRONSKI, A.; ABASHKIN, V.; LYTVYN, O.; SENCHENKO, O.; GUBANOVA, A. (Tehnica UTM, 2015)
    Properties of nanomultilayer As2S3:Mn systems and peculiarities of holographic gratings recording with their use are considered in this report. Optical constants were obtained from transmission data, spectral dependencies ...
  • Photoinduced Anisotropy in Azopolymer Studied by Spectroscopic and Polarimetric Parameters 
    LOSMANSCHII, C.; ACHIMOVA, E.; ABASHKIN, V.; BOTNARI, V.; MESHALKIN, A. (Universitatea Tehnică a Moldovei, 2021)
    We discuss methods for synthesis and fabrication of photosensitive thin azopolymer films. Spectroscopy of films presents information as about nonactinic and recording wavelengths as a for refraction index calculations by ...
  • Properties of Carbazole-based Azopolymer Used in Formation of Photoinduced Surface Relief Gratings 
    MESHALKIN, A.; ROBU, S.; ACHIMOVA, E.; BOIARINOV, Yu.; PRISACAR, A.; SHEPEL, D.; ABASHKIN, V.; TRIDUH, G. (Tehnica UTM, 2015)
    New carbazole-based azopolymer was synthesized, characterized and applied for formation of photoinduced surface relief gratings. The surface modulation of spin-coated azopolymer film depending on the different polarization ...
  • Surface relief formation in Yb doped As2S3–Se nanomultilayer structures 
    PAIUK, O.; MESHALKIN, A.; STRONSKI, A.; ACHIMOVA, E.; ABASHKIN, V.; PRISACAR, A.; TRIDUH, G.; KORCHOVYI, A.; OLEKSENKO, P. (Tehnica UTM, 2019)
    Chalcogenide glasses and films are promising materials for application in optoelectronics and photonics. Nanomultilayer structures based on chalcogenide glasses attract much attention due to their property of direct ...
