    • Color holographic reconstruction using multiple SLMs and LED illumination 

      Yaraş, F.; Onural, L. (S P I E - International Society for Optical Engineering, 2009)
      A color holographic reconstruction technique by using three light emitting diodes (LEDs) is described. Reflective type phase-only spatial light modulators (SLMs) are used since they are suitable for in-line phase holograms. ...
    • An overview of research in 3DTV 

      Onural, L. (2007)
      3DTV is regarded by the experts and the general public as the next major step in video technologies. The ghost-like images of remote persons or objects are already depicted in many futuristic movies; both entertainment ...
    • Processing of optically-captured digital holograms for three-dimensional display 

      Naughton, T.J.; Kreis, T.; Onural L.; Ferraro P.; Depeursinge, C.; Emery, Y.; Hennelly, B.M.; Kujawiñska, M. (2009)
      In digital holography, holograms are usually optically captured and then two-dimensional slices of the reconstruction volume are reconstructed by computer and displayed on a two-dimensional display. When the recording is ...
    • Quality comparison and acceleration for digital hologram generation method based on segmentation 

      Kang, H.; Yaraş, F.; Onural, L. (IEEE, 2009)
      A holographic fringe pattern generation methods is based on Fraunhofer diffraction and subsequent segmentation and approximation of the fringe pattern. Several modifications of the original algorithm are already proposed ...
    • Real-time color holographic video display system 

      Yaraş, F.; Kang, H.; Onural, L. (IEEE, 2009)
      A real-time multi-GPU color holographic video display system computes holograms from 3D video of a rigid object. System has three main stages; client, server and optics. 3D coordinate and texture information are kept in ...
    • Signal processing problems and algorithms in display side of 3DTV 

      Ulusoy, E.; Esmer G.B.; Ozaktas, H., M.; Onural L.; Gotchev, A.; Uzunov V. (2006)
      Two important signal processing problems in the display side of a holographic 3DTV are the computation of the diffraction field of a 3D object from its abstract representation, and determination of the best display ...
    • Technique for reconstructing a surface shape for measuring coordinates 

      Saĭnov, V. Kh.; Kharizanova, Zh. I.; Stoĭkova, E. V.; Ozaktas, Kh. M.; Onural, L. (Optical Society of America, 2006)
      This paper describes a method of projecting interference fringes as one of the most accessible techniques for measuring the coordinates of objects and scenes that can be used when solving inverse problems in dynamic ...
