Speckle photography with different pupils in a multiple-exposure scheme
(Optical Society of America, 2000-01-01)
The use of different multiple-aperture pupils for recording each image in speckle photography is proposed -- The introduction of suitable spatial frequency carriers, by internally modulating imaged speckles, allows one to ...
Analysis of vibrations in a plate using interferometric methods
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 ...
