    Infrared digital holography applications for virtual museums and diagnostics of cultural heritage
    (SPIE, 2011) Paturzo, M.; Pelagotti, A.; Geltrude, A.; Locatelli, M.; Poggi P.; Meucci, R.; Ferraro P.; Stoykova, E.; Yaraş F.; Yöntem, A. Özgür; Kang H.; Onural, Levent
    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 to compose dynamic 3D scenes that, then, are optically reconstructed by means of spatial light modulators (SLMs) using an illumination wavelength of 532 nm. This kind of reconstruction allows to obtain a 3D imaging of the statuettes that could be exploited for virtual museums. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

    Visible reconstruction by a circular holographic display from digital holograms recorded under infrared illumination
    (Optical Society of America, 2012-07-20) Stoykova, E.; Yaras, F.; Kang, H.; Onural, L.; Geltrude, A.; Locatelli, M.; Paturzo, M.; Pelagotti, A.; Meucci, R.; Ferraro, P.
    A circular holographic display that consists of phase-only spatial light modulators is used to reconstruct images in visible light from digital holograms recorded under infrared (10.6 μm) illumination. The reconstruction yields a holographic digital video display of a three-dimensional ghostlike image of an object floating in space where observers can move and rotate around it.
