Analysis of vibrations in a plate using interferometric methods 

Ángel-Toro, Luciano; Prieto, Daniel Velasquez; Rueda Muñóz, Edgar Alberto (SPIE, 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 ...

Logic operations by using modulated speckle 

Tebaldi, Myrian; Ángel-Toro, Luciano; Trivi, Marcelo; Bolognini, Néstor (SPIE, 2001-08-14)
An alternative image multiplexing technique is proposed. In the arrangement implemented, the input is imaged by introducing a multiple aperture pupil in the imaging lens. Then, the speckle pattern is modulated by several ...

Soap film analysis by speckle interferometer 

Tebaldi, M.; Ángel, L.; Trivi, M.; Bolognini, N. (SPIE-INT SOC OPTICAL ENGINEERING, 2003-01-01)
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 ...

DC term filtering techniques in digital holography 

Velásquez-Prieto, Daniel; García Sucerquia, Jorge Iván; Herrera Ramírez, Jorge Alexis (SPIE, 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 ...
