چکیده
In this study , electro chemical methods and th e di gital holograph ic reconstruction technique were combined to detect the localized scratch-induced corrosion process of Alloy 690 in 0.50 mol dm-3 H2SO4 containing 0.10 mol dm-3 Na Cl. Th e nu merical re construction method ha s been proved to be an effective technique to detect changes of solution concentration. One can obtain direct infor mation fro m th e reconstru cted i mages and c apture subtle more revealing ch anges. It provides a method to d etect locali zed corrosion arisi ng from scratches.

Mapping the concentration changes during the dynamic processes of crevice corrosion by digital holographic reconstruction
The dynamic process of crevice corrosion during anodic dissolution of a crevice electrode in a 5.0 mmol dm-3 NaCl solution has been studied by digital holographic reconstruction. Digital holographic reconstruction has been proved to be an effective and in situ technique to detect the changes in the solution concentration because useful and direct information can be obtained from the three-dimen...
متن کاملComprehensive Solutions for Removal of Dust and Scratches from Images
Dust, scratches or hair on originals (prints, slides or negatives) distinctly appear as light or dark artifacts on a scan. These unsightly artifacts have become a major consumer concern. There are several scenarios for removal of dust and scratch artifacts. One scenario is during acquisition, e.g., while scanning a photographic media. Another is artifact removal from a digital image in an image...
متن کاملMeasuring the deposited energy from a non-ionizing laser beam in water by digital holographic interferometry
Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...
متن کاملDetection and Removal of Line Scratches in Motion Picture Films
Line scratches are common degradations in motion picture films. This paper presents an efficient method for line scratches detection strengthened by a Kalman filter. A new interpolation technique, dealing with both low and high frequencies (i.e. film grain) around the line artifacts, is investigated to achieve a nearby invisible reconstruction of damaged areas. Our line scratches detection and ...
متن کاملNatural linearization for corrosion identification
We consider the numerical solution of a nonlinear problem arising in in nondestructive detection of a corrosion at a hidden surface of a conductor. The problem can be naturally linearized and reduced to an elliptic Cauchy problem. In this paper we describe and test a regularized reconstruction algorithm based on a regularization by discretization, where the discretization level is chosen in dat...
