OverviewAI-generated summary
Óscar Martínez-Graullera's research centers on the development and application of ultrasonic imaging systems, particularly for non-destructive testing (NDT) and three-dimensional imaging. His work has involved the design of specialized ultrasonic transducer arrays, including 2D arrays based on Fermat spirals and 64-element 2D piezoelectric arrays for 3D imaging. He has investigated advanced signal processing techniques such as Synthetic Aperture Focusing Technique (SAFT) and progressive focusing correction for improved beamforming and image enhancement. Martínez-Graullera has also explored the use of Graphics Processing Units (GPUs) to accelerate beamforming processes in ultrasonic imaging. His publications address damage characterization using guided-wave linear arrays and image compounding, as well as the design of small 2D ultrasonic arrays for NDT applications. He has a documented h-index of 16 across 135 publications, with a total of 816 citations. Key collaborators include Kevin R. Lewelling, Robert Murphree, and Kirk D. Kimery.
