Information retrieval from holographic interferograms: Fundamentals and problems [PDF]
Holographic interferograms can contain large amounts of information about flow and temperature fields. Their information content can be very high because they can be viewed from many different directions. This multidirectionality, and fringe localization

Modes of vibration and sound radiation from the HANG
Archives of Acoustics, 2014 The HANG is a new hand-played steel instrument developed by PANArt in Switzerland. We describe the modes of vibration, observed by holographic interferometry and the sound radiation from the instrument observed by measuring the sound intensity in an ...

Reconstruction of a three-dimensional, transonic rotor flow field from holographic interferogram data [PDF]
Holographic interferometry and computerized aided tomography (CAT) are used to determine the transonic velocity field of a model rotor blade in hover. A pulsed ruby laser recorded 40 interferograms with a 2 ft dia view field near the model rotor blade ...
