3D Microwave Imaging Technology For Damage Detection of Concrete Structures
Various nondestructive evaluation (NDE) techniques have been studied to locate steel rebars or dowel, and to detect invisible damage such as voids and cracks inside concrete and debonding between rebars and concrete caused by corrosions and earthquakes. In this study, the authors developed 3-dimensional (3D) electromagnetic (EM) imaging technology to detect such damage and to identify exact loc...
متن کاملPerformance of Ultrasonic Imaging with Frequency Domain Saft (f-saft)
The time and Fourier domain Synthetic Aperture Focusing Technique (SAFT and FSAFT) have been used to improve both sensitivity and lateral resolution of ultrasonic NDT. Following acquisition of signals over the surface of the tested piece, SAFT identifies a defect by summing all the signals within a certain area (the aperture) after giving proper time-delays. FSAFT, although using the same data,...
متن کاملPhase Sensitive Detection and Classification of Defects in Concrete Structures by Ultrasonic and Electromagnetic Imaging Techniques
Many applications of imaging techniques like diffraction tomography demonstrate their ability to image the interior of huge structures like bridges. One problem of testing concrete bridges are grouting defects in tendon ducts which may lead to corrosion of tendons yielding a degradation of the stability of the whole structure. Ultrasound is able to penetrate the tendon ducts and therefore it ma...
متن کاملUltrasonic Array Imaging Method for Concrete Materials
Because of the need of rapid detection of internal defects and embedded object in concrete structures, a ultrasonic detecting method with linear array transducers is presented here, which is the high-resolution and efficient imaging technique for concrete materials by combining with synthetic aperture focusing technique (SAFT). At first, simulation data of array detection are processed to be am...
متن کامل3D-SAFT Ultrasonic Inspection Equipment “MatrixeyeTM”
3D ultrasonic inspection equipment “Matrixeye” can visualize defects as 3D image with good resolution by the 3D SAFT (Synthetic Aperture Focusing Technique) imaging method. High-speed 3D SAFT imaging process can be achieved by the developed parallel signal process of the ultrasonic echo data collected by a linear or a matrix-array ultrasonic probe. It has the following features. •3D image with ...
