    • Capture, processing, and display of real-world 3D objects using digital holography 

      Naughton, T.J.; Falldorf, C.; Onural L.; Ferraro P.; Depeursinge, C.; Krueger, S.; Emery, Y.; Hennelly, B.M.; Kujawifiska, M. (2010)
      "Digital holography for 3D and 4D real-world objects' capture, processing, and display" (acronym "Real 3D") is a research project funded under the Information and Communication Technologies theme of the European Commission's ...
    • Computation of holographic patterns between tilted planes 

      Esmer, G. B.; Onural, L. (S P I E - International Society for Optical Engineering, 2006)
      Computation of the diffraction pattern that gives the desired reconstruction of an object upon proper illumination is an important process in computer generated holography. A fast computational method, based on the plane ...
    • Current research activities on holographic video displays 

      Onural, L.; Yaraş, F.; Kang, H. (S P I E - International Society for Optical Engineering, 2010)
      "True 3D" display technologies target replication of physical volume light distributions. Holography is a promising true 3D technique. Widespread utilization of holographic 3D video displays is hindered by current technological ...
    • Digital decoding of in-line holograms 

      Onural, L.; Scott, P. D. (SPIE, 1987)
      Digitally sampled in-line holograms may be linearly filtered to reconstruct a representation of the original object distribution, thereby decoding the information contained in the hologram. The decoding process is performed ...
    • Digital holographic three-dimensional video displays 

      Onural, L.; Yaras, F.; Kang, H. (IEEE, 2011-02-04)
      Holography aims to record and regenerate volume filling light fields to reproduce ghost-like 3-D images that are optically indistinguishable from their physical 3-D originals. Digital holographic video displays are ...
    • Feature issue of digital holography and 3D imaging (DH) introduction 

      Hayasaki, Y.; Zhou, C.; Popescu G.; Onural L. (Optical Society of American (OSA), 2014)
      The OSA Topical Meeting "Digital Holography and 3D Imaging (DH)," was held in Seattle, Washington, July 13-17, 2014. Feature issues based on the DH meeting series have been released by Applied Optics (AO) since 2007. This ...
    • Infrared digital holography applications for virtual museums and diagnostics of cultural heritage 

      Paturzo, M.; Pelagotti, A.; Geltrude, A.; Locatelli, M.; Poggi P.; Meucci, R.; Ferraro P.; Stoykova, E.; Yaraş F.; Özgür Yontem, A.; Kang H.; Onural L. (2011)
      Infrared digital holograms of different statuettes are acquired. For each object, a sequence of holograms is recorded rotating the statuette with an angular step of few degrees. The holograms of the moving objects are used ...
    • Preface 

      Healy, J. J.; Kutay, M. A.; Özaktaş, Haldun M.; Sheridan, J. T. (Springer, New York, 2016)
    • 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 ...
    • Some mathematical properties of the uniformly sampled quadratic phase function and associated issues in digital Fresnel diffraction simulations 

      Onural, L. (SPIE - International Society for Optical Engineering, 2004)
      The quadratic phase function is fundamental in describing and computing wave-propagation-related phenomena under the Fresnel approximation; it is also frequently used in many signal processing algorithms. This function has ...
    • State of the art in holographic displays: a survey 

      Yaraş, F.; Kang, H.; Onural, L. (IEEE, 2010-05-27)
      True-3D imaging and display systems are based on physical duplication of light distribution. Holography is a true-3D technique. There are significant developments in electro-holographic displays in recent years. Liquid ...
