  • Fiber Optic Speckle Interferometry for Intrusion Monitoring Systems 
    CULEAC, I.; BORSCIOV, V.; VERLAN, V.; COJOCARU, I.; IOVU, M.; CIORNEA, V.; BUZDUGAN, A. (Technical University of Moldova, 2017)
    A speckle based fiber-optic technique for perimeter intrusion-monitoring systems is discussed. The method is based on the effect of variation of the speckle pattern in the far-field of a multimode fiber. Computer processing ...
  • Gas sensors based on optical fiber coated with nanocrystalline TiO2 and nanofibrous ZnO 
    GHIMPU, Lidia; PLESCO, Irina; URSACHI, Veaceslav; TIGINYANU, Ion; ZARRELLI, Mauro; ZOTTI, Aldobeneddetto; BORRIELLO, Anna (Technical University of Moldova, 2017)
    The paper is divided into two main sections: first, we report on magnetron sputtering of zinc oxide and titanium dioxide; second, the results of the investigation of the morphology and sensing characteristics of the optical ...
  • Optical fibers and dispersion in optical fibers Types of dispersion 
    MOROZAN, Pavel; SOROCHIN, Serafima; LACHI, Arina; SAVA, Lilia (Technical University of Moldova, 2017)
    In this paper ensue to be characterized all types of optical fibers and their features, also the phenomenon of dispersion and the reasons of its appearance or occurance. By means of all pictures shown below in the paper, ...
