    Stemming from the results of our earlier investigations, the concept of area scintillation is introduced, which takes into account the intensity distribution over the receiver plane. In this context, the area scintillation ...
  • Concept of Information, Discrete Entropy and Mutual Information

    In this chapter, we will try to explain the concept of information, discrete entropy and mutual information in details. To master on the information theory subjects, the reader should have a knowledge of probability and ...
  • Convergence of general beams into Gaussian intensity profiles after propagation in turbulent atmosphere 
    Eyyuboğlu, Halil T.; Baykal, Yahya; Sermutlu, Emre (Elsevier Science, 2006-09)
    It is shown that a general shaped laser beam will eventually approach a Gaussian average intensity profile after propagation in turbulent atmosphere. In our formulation, source field at the exit plane of the laser is taken ...

    Eyyuboğlu, Halil T. (Taylor&Francis Ltd., 2016)
    We apply amplitude corrections to a truncated Bessel beam that has propagated through turbulent atmosphere modelled by random phase screens. These corrections are realized via transmitting an unmodulated beam in parallel ...
