Principles of a Defect Localisation in Nonlinear Ultrasonic Mixing Impulse Spectroscopy
Keywords:nonlinear ultrasonic mixing spectroscopy, sensitivity, impulse excitation, localization
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 in delay of the second excitation pulse can to obtain the image distribution of defects on the tested body in a 2D plane in few seconds.
