Main Research Directions

  • The development of physical methods of nondestructive investigation of processes in deformable continuous media; principles and means of real-time monitoring of physical fields accompanying them.
  • Dynamic holography in photorefractive crystals and the development of adaptive methods of processing all-fiber interferometer signals on their basis.
  • Correlation methods of processing electronic speckle interferograms.
  • Research into optical properties of natural and artificial nanostructures and into the interaction between laser radiation and nanostructures.

     

Principal Results

  • Fundamental processes of NLO interactions between dimensionally incoherent light waves in photorefractive crystals have been investigated.
  • A research has been made into the dynamics of changes in the speckle radiation field patterns at the outlet of a one-fiber multimode interferometer.
  • Fundamental and applied research has been made into the development of hardware components of fiber-optic measurement networks for creating "sensitive surfaces".
  • Physical and technological grounds of developing mobile and scalable segment-type fiber-optic measurement network have been elaborated.
  • Methods of dynamic object recognition based on AI technology have been developed.
  • Processes of dynamic scattering of coherent radiation in liquid-phase nanocomposites have been investigated.
