Effective Defect Features Extraction for Laser Ultrasonic Signal Processing by Using Time–Frequency Analysis

Effective Defect Features Extraction for Laser Ultrasonic Signal Processing by Using Time–Frequency Analysis

The time-frequency analysis (TFA) by wavelet transform is adopted for the laser ultrasonic signal processing, and the effective features extraction of the material defect is obtained. The TFA is adopted here to analyze the laser-generated surface acoustic wave (SAW) signal which contains the defect...
