摘要
Advanced ultrasonic detection techniques are presently developed for applications in all three dimensions (1D-3D) employing conventional transducers and laser methods. In practical applications predominantly versatile piezo-transducers and interdigital structures are used, while scientific research and development are mainly based on contactfree laser methods. Examples are given for the use of guided bulk waves (3D) in monitoring pipes and rails, linear and nonlinear surface acoustic waves (2D) in NDE and failure analysis, and the present development of linear and nonlinear wedge waves (1D) as new diagnostic tools.
