Speckle tomography of turbulent flows with density fluctuations

Real-Time Colour Holographic Interferometry (from Holographic Plate to Digital Hologram)

“…They present holographic interferometric tomography for limited data reconstruction to measure an asymmetric temperature field. Other researchers designed an optical scheme for obtaining specklegrams simultaneously in four directions (Fomin, 1998;Fomin et al, 2002) or built an interferometric tomography apparatus with six viewing directions from which multidirectional data sets were analyzed following a method of examining spatial coherence (Pellicia-Kraft & Watt, 2000, 2001. The same approach is used by researchers developing digital holographic interferometric techniques.…”
