| 摘要 |
The present invention generally relates to improved non-destructive thickness measurement systems and methods. Embodiments of the present invention utilize quarter wave resonant frequency to measure the thickness of high-temperature pipe walls. In one embodiment, an improved non-destructive thickness measurement system is provided that utilizes Gaussian white noise to produce maximum mechanical resonance in the pipe wall and laser vibrometers to detect the pipe wall's maximum displacement.
