Method and system for obtaining near-surface characteristics of materials using ultrasonic Rayleigh waves |
摘要 |
In a method for obtaining near-surface characteristics of a material, a series of single frequency ultrasonic Rayleigh waves are generated, with a generating system, in the material. The Rayleigh waves are detected with a detection system remote from the generating system. Velocities of the detected Rayleigh waves are determined at the selected frequencies. A depth profile of one or more characteristics of the material is prepared based on the determined Rayleigh wave velocities.
