  • Speckle interferometric technique to assess soap films 

    Ángel Toro, Luciano; Bolognini, Néstor Alberto; Tebaldi, Myrian Cristina; Trivi, Marcelo Ricardo (Elsevier B.V., 2003-10-17)
    An speckle interferometric technique to monitor the thinning process of vertical soap film before the film rupture is presented -- The interferometric arrangement consists in a double aperture pupil optical system which ...
  • Analysis of vibrations in a plate using interferometric methods 

    Ángel-Toro, Luciano; Prieto, Daniel Velasquez; Rueda Muñóz, Edgar Alberto (SPIE; Grupo de Investigación de Óptica Aplicada; Escuela de Ingeniería, 2004-10-21)
    In this work some frequencies and modes of vibration of a thin plate were determined using interferometric methods like: real-time holographic interferometry, time-average holographic interferometry, digital speckle pattern ...
  • Double aperture speckle method using a BSO crystal for in plane displacement 

    Trivi, Marcelo Ricardo; Tebaldi, Myrian Cristina; Bolognini, Néstor Alberto; Ángel Toro, Luciano (SPIE, 1999-07-06)
    The possibility of using a BSO crystal as a recording medium of specklegrams with carrying frequency fringes, to storage multiple interferograms, for uniform in-plane displacements, is presented. Experimental results are ...
  • DC term filtering techniques in digital holography 

    Velásquez-Prieto, Daniel; García Sucerquia, Jorge Iván; Herrera Ramírez, Jorge Alexis (SPIE; Grupo de Investigación de Óptica Aplicada; Escuela de Ingeniería, 2004-10-21)
    In numerical hologram reconstruction like in optical holography, there exist different diffraction orders, which many times produce difficulties for the image visualizations. In numerical reconstruction, the filtering of ...
  • Contrast inversion in the Lau phenomena implemented with a photorefractive grating 

    Ángel Toro, Luciano; Tebaldi, Myrian Cristina; Bolognini, Néstor Alberto (SPIE, 1999-07-06)
    It was implemented the Lau effect with a grating registered in a BSO crystal. Two different arrangement were analyzed. In both cases, it is possible to control the visibility and to produce the contrast inversion of fringes, ...
