Holographic interferometry as a method to detect welding failures on ribbed iron structures
(SPIE, 2013-07-22)
Metallic structures made of ribbed iron bars (ADN-420) are of common use in sheds and supporting structures. Usually, trusses are constructed with many pieces of ribbed iron bars, combined together through a welding process. ...
Characterization of drying paint coatings by dynamic speckle and holographic interferometry measurements
(Optical Society of America, 2016-05)
In this work we implemented dynamic speckle and holographic interferometry techniques to characterize the drying process of solvent-based paint coatings. We propose a simple way to estimate drying time by measuring speckle ...
Dynamic analysis of a deforming membrane by digital holographic interferometry
(Elsevier, 2015-04)
In this work we performed an analysis of the deformations suffered by a membrane by means of the non-invasive nor destructive digital holographic interferometry technique (DHI). This technique consists in recording holograms ...
Mastication effort study using photorefractive holographic interferometry technique
(ELSEVIER SCI LTD, 2010)
The purpose of this work was the force-displacement response analysis of the masticatory process in a dried human skull by Double-Exposure Photorefractive Holographic Interferometry Technique (2E-PRHI). The load concentration ...
Multi-wavelength holography in Bi12TiO20 crystals: Applications in refractometry
(Elsevier B.V., 2006-07-15)
We present a recent development in holography with multimode, large free-spectral range (FSR) diode lasers in photorefractive sillenite crystals. A novel refractometry method based on this type of holographic recording in ...
Enhanced multiwavelength holographic profilometry by laser mode selection
(Spie-soc Photoptical Instrumentation Engineers, 2007-07-01)
A method for improving the accuracy of surface shape measurement by multiwavelength holography is presented. In our holographic setup, a Bi12TiO20 photorefractive crystal was the holographic recording medium, and a multimode ...

Plasmonic structures fabricated by interference lithography for sensor applications
(2009-11-18)
In this work we demonstrate the use of holographic lithography for generation of large area plasmonic periodic structures. Submicrometric array of holes, with different periods and thickness, were recorded in gold films, ...
