Combined denoising filter for fringe pattern in electronic speckle shearing pattern interferometry [PDF]
, 2015 We propose an effective image denoising filter that combines an improved spin filter (ISF) and wave atoms thresholding (WA) to remove the noise of fringe patterns in electronic speckle shearing pattern interferometry.

Adaptive Aperture Defocused Digital Speckle Photography
, 2005 Speckle photography can be used to monitor deformations of solid surfaces. The measuring characteristics, such as range or lateral resolution depend heavily on the optical recording and illumination set-up.

Imaging the Haro 6-10 Infrared Companion [PDF]
, 1999 We present an infrared imaging study of the low-mass pre-main-sequence binary system Haro 6-10. This system is one of a handful in which the optically visible primary has the characteristics of a normal T Tauri star, while the secondary is a so-called ...

A hybrid technique for residual stress analysis through stress function fitting
Latin American Journal of Solids and StructuresThis work presents a hybrid experimental theoretical technique for residual stresses analysis of mechanical components. It was used the blind hole technique along with the Electronic Speckle Pattern Interferometry (ESPI) method and Airy stress functions ...
