Quick Simple and Sensitive Tomography by Nonlinear Ultrasonic Mixing Spectroscopy

Popis výsledku v původním jazyce

Principles of nonlinear ultrasonic mixing impulse spectroscopy (NUMIS) show great potential advantages in comparison with other nonlinear ultrasonic methods. It is first of all from the point of view of sensitivity and possibility of quick, simple and precise localization of a defect. This paper elaborates on the principles and algorithms of calculation of the defect place for this method. The point idealization of ultrasonic transducers and receivers are supposed for this aim. A successive increase indelay of the second excitation pulse can to obtain the image distribution of defects on the tested body in a 2D plane in few seconds. The main idea of this method consists in sending of two impulses (bursts) with the armonic signals with different frequencies f1 and f2. These bursts are mutually time shifted in successive steps. When two waves come across in the place of defect with nonlinear roperties, the new frequency component with different frequency fd will be created. Optimum choi
