  • 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 ...
  • Multiple-aperture speckle method applied to local displacement measurements 

    Ángel-Toro, Luciano; Tebaldi, Myrian; Bologninic, Néstor (Elsevier B.V; Grupo de Investigación de Óptica Aplicada; Escuela de Ciencias y Humanidades, 2007)
    The goal of this work is to analyze the measurement capability of the modified speckle photography technique that uses different multiple aperture pupils in a multiple exposure scheme. In particular, the rotation case is ...
  • Soap film analysis by speckle interferometer 

    Tebaldi, Myrian; Ángel-Toro, Luciano; Trivi, Marcelo; Bolognini, Néstor (SPIE; Grupo de Investigación de Óptica Aplicada; Escuela de Ciencias y Humanidades, 2003-11-18)
    In this paper a soap film is characterized by using a speckle interferometer. The arrangement consists of a double-exposure specklegram obtained through a double-aperture system, by introducing a wedge in front of one ...
