  • 3D studies of orobanche cumana seeds by digital holographic microscopy 
    DUCA, Maria; PEDRINI, Giancarlo; CLAUS, Daniel; ABASKIN, Vladimir; ACHIMOVA, Elena; GLIJIN, Aliona; ACCIU, Adriana (Tehnica UTM, 2014)
    Combining microscopy and digital holography (DH) offers the unique advantage of simultaneously capturing complete 3D information about the specimen, and under coherent illumination it has been investigated for continuous ...
  • Computer- assisted electron beam recording of patterns in As2S3 films 
    ABASHKIN, Vladimir; ACHIMOVA, Elena; SERGHEEV, Sergei; PRISACAR, Alecsandr (Tehnica UTM, 2013)
    In this paper, we present the PC-assisted e-beam recording of some diffraction structures in As2S3 thin films with thickness about 1 μm. The square surfaces occupied by holograms on the film were from 400 x 400 μm2 up to ...
  • Influence of thickness and polarization on diffraction efficiency of direct patterned diffraction gratings in carbazole-based azopolymer films 
    LOSMANSCHII, Constantin; MESHALKIN, Alexei; ACHIMOVA, Elena; ABASHKIN, Vladimir; PRISACAR, Alexandr; CAZAC, Veronica; POGREBNOI, Serghei; MACAEV, Fliur (Technical University of Moldova, 2017)
    In this paper we report on direct holographic recording of surface relief gratings in carbazole-based azopolymers. Azo dye Disperse Orange 3 was chemically bonded to oligomer poly-N-(epoxypropyl carbazole) making surface ...
  • Investigations of optical properties of As2S3-Se nanomultilayers 
    ABASHKIN, Vladimir; ACHIMOVA, Elena; KRYSKOV, Tezarii; MESHALKIN, Alexei; PRISACAR, Alexander; TRIDUH, Ghenadii; VLCEK, Miroslav (Tehnica UTM, 2013)
    The chalcogenide glasses are interesting materials for investigation of nanostructural properties possessing unique characteristics which are different from those in oxide and halide glasses, i.e. molecular (low-dimensional) ...
  • Nanocomposite Films Based on Photosensitive Azopolymer with Gold Nanoparticles: Synthesis, Film Deposition, Diffractive Optical Elements Recording and Characterization 
    ACHIMOVA, Elena; ABASHKIN, Vladimir; MESHALKIN, Alexei; LOSMANSCHII, Constantin; BOTNARI, Vladislav; PEDRINI, Giancarlo (Springer Nature Switzerland, 2023)
    In the present study, the photosensitive nanocomposite was fabricated based on azopolymer and Au nanoparticles (Azo-Au NPs). For the first time, the synthesized polymeric poly-N-(2,3-epoxypropyl) carbazole with azo dye SY ...
  • Optical Properties and Photoinduced Anisotropy of PEPC-co-SY3 Nanocomposite 
    LOŞMANSCHII, Constantin; ACHIMOVA, Elena; ABASKIN, Vladimir; MESALCHIN, Alexei; PRISACAR, Alexandr; BOTNARI, Vladislav (Springer Nature Switzerland, 2023)
    In the present work, the optical properties of the PEPC-co-SY3 nanocomposite doped with gold nanoparticles are brought to light. The samples were prepared with 3 different concentrations of Au as well as a control sample ...
  • Phase Grating Application for Digital Holographic Imaging 
    MESHALKIN, Alexei; KAZAK, Veronika; SHEVKUNOV, Igor; ACHIMOVA, Elena; ABASHKIN, Vladimir; KATKOVNIK, Vladimir (Technical University of Moldova, 2017)
    An application of phase harmonic grating for digital holographic imaging was modeled. The process of digital hologram recording was simulated in off-axis geometry combined by placing a grating in reference or object beam ...
  • The self-mixing interferometer setup modeled by optical soft 
    ACHIMOVA, Elena (Technical University of Moldova, 2017)
    The capability to model optical instrument prior to detailed design and analyses is very powerful tool that can save schedule time, instrument implementation costs, and gives great insight into many facets of optical ...
