    • Accumulated Gouy phase shift in Gaussian beam propagation through first-order optical systems 

      Erden, M. F.; Özaktaş, Haldun M. (Optical Society of America, 1997-09)
      We define the accumulated Gouy phase shift as the on-axis phase accumulated by a Gaussian beam in passing through an optical system, in excess of the phase accumulated by a plane wave. We give an expression for the accumulated ...

    • Fourier transforms of fractional order and their optical interpretation 

      Özaktaş, Haldun M.; Mendlovic, D. (Elsevier, 1993)
      Fourier transforms of fractional order a are defined in a manner such that the common Fourier transform is a special case with order a=1. An optical interpretation is provided in terms of quadratic graded index media and ...

    • Self Fourier functions and fractional Fourier transforms 

      Mendlovic, D.; Özaktaş, Haldun M.; Lohmann, A. W. (Elsevier, 1994)
      Self Fourier functions and fractional Fourier transforms are two concepts that have been discussed recently. Investigated is the combination of these two concepts: self fractional Fourier functions and the fractional Fourier ...
