Multiplicative electronic speckle-pattern interferometry fringes

Applied Optics, 2000
A theoretical analysis of fringe patterns and its experimental corroboration obtained by multiplication of two speckled images with electronic speckle-pattern interferometry (ESPI) are reported. A specifically designed digital filter is used to enhance the contrast and visibility of the inherently noisy multiplication fringes.

Electronic speckle pattern interferometry using vortex beams

Optics Letters, 2011
We show that it is possible to perform electronic speckle pattern interferometry (ESPI) using, for the first time to our knowledge, vortex beams as the reference beam. The technique we propose is easy to implement, and the advantages obtained are, among others, environmental stability, lower processing time, and the possibility to switch between ...

Electronic Speckle Pattern Interferometry

Topical Meeting on Holography, 1986
Holographic workstations are now enabling the advantages of Holographic Interferometry (HI) to be taken outside research laboratories and placed alongside manufacturing equipment. Most rigidization problems have been overcome but two handicaps still limit its widespread application.
