... tubing. Laser-generated interrogating ultrasonic waves in the tubing were detected by use of a fiber-tip interferometer (FTI) and a continuous wave HeNe laser. The time-frequency analysis of the generated dispersive waves was performed using the Gabor wavelet transform (GWT) that effectively decomposed...
