Backscatter Imaging for Guided Wave Detection of Defects in Rails
碩士 === 國立交通大學 === 機械工程系所 === 106 === This thesis successfully develops a backscatter imaging method for guided wave detection of defects in rail. A directional filter based on two-dimensional fast Fourier transform and air-coupled ultrasonic (ACU) transducers have been employed. The spatial frequenc...
