A Sparse Reconstruction Algorithm for Ultrasonic Images in Nondestructive Testing
Ultrasound imaging systems (UIS) are essential tools in nondestructive testing (NDT). In general, the quality of images depends on two factors: system hardware features and image reconstruction algorithms. This paper presents a new image reconstruction algorithm for ultrasonic NDT. The algorithm reconstructs images from A-scan signals acquired by an ultrasonic imaging system with a monostatic t...
متن کاملA Sparse Reconstruction Algorithm for Multi-Frequency Radio Images
In radio interferometry, every pair of antennas in an array defines one sampling point in the Fourier domain of the sky image. By combining information from different wavelengths, sample coverage—and therefore reconstruction quality—can be increased. However, the images at different wavelengths can be dramatically dissimilar; this fact must be taken into account when reconstructing multi-freque...
متن کاملRegularized Richardson-Lucy Algorithm for Sparse Reconstruction of Poissonian Images
Restoration of digital images from their degraded measurements has always been a problem of great theoretical and practical importance in numerous applications of imaging sciences. A specific solution to the problem of image restoration is generally determined by the nature of degradation phenomenon as well as by the statistical properties of measurement noises. The present study is concerned w...
متن کاملUltrasonic Nondestructive Testing Method for Evaluation of Annular Seals
Drilling boreholes is common practice in geotechnical and geoenvironmental investigations and in various other ex ploration, testing, and monitoring appli cations. When a casing is placed in a borehole an annular space is created be tween the casing and the surrounding soil. If not properly sealed, this annular space can be a potential path for trans port of contaminants in the subsurface e...
متن کاملUltrasonic Guided Wave Nondestructive Testing for Helicopter Rotor Blade
Ultrasonic guided waves are used to detect the delamination between skin and honeycomb of a composite helicopter rotor blade. Theoretical work is carried out for guided waves in the trailing edge of a rotor blade, which is a multilayer composite skin/NOMEX half space structure. The dispersion relation is obtained with the global matrix method. Theoretically driven experiments are conducted on a...
