    • Beyond Nyquist sampling: a cost-based approach 

      Özçelikkale, A.; Haldun M. Özaktaş (Optical Society of America, 2013)
      A sampling-based framework for finding the optimal representation of a finite energy optical field using a finite number of bits is presented. For a given bit budget, we determine the optimum number and spacing of the ...
    • Phase retrieval from electric field intensity for wide angle optical fields 

      Külçe, Onur; Onural, Levent (OSA, 2017)
      An intensity preserving scalar to vector electric field mapping, in a wave propagation environment, based on a filtering procedure is proposed. In a phase retrieval problem, the proposed mapping outperforms the conventional ...
    • Representation of optical fields using finite numbers of bits 

      Özçelikkale, A.; Haldun M. Özaktaş (Optical Society of America, 2012-06-04)
      We consider the problem of representation of a finite-energy optical field, with a finite number of bits. The optical field is represented with a finite number of uniformly spaced finite-accuracy samples (there is a finite ...
    • Signal processing issues in diffraction and holographic 3DTV 

      Onural, Levent; Özaktaş, Haldun M. (IEEE, 2005)
      Image capture and image display will most likely be decoupled in future 3DTV systems. For this reason, as well as the need to convert abstract representations to display driver signals, and the need to explicitly consider ...
