Soap film analysis by speckle interferometer
(SPIE, 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 ...
Phase-object detection by use of double-exposure fringe-modulated speckle patterns
(OSA, 2003-01)
We study the properties of a double-exposure image specklegram of a diffuse object obtained by use of a doubleaperture pupil. A phase object is placed in front of one aperture during the first or the second exposure. Also, ...
