Abstract
Relevant resonance response characteristics of a sample are determined for use in characterizing the sample for non-destructive testing. The sample is excited by an exciting mechanical input at a plurality of ultrasonic frequencies. The response is separated into in-phase and quadrature components and the resonance response characteristics are computed from the in-phase and quadrature components. Apparatus for obtaining the relevant response characteristics includes a frequency generator for inputting an exciting ultrasonic frequency to the sample. A transducer outputs a response of the sample to the exciting ultrasonic frequency. A dynamic signal analyzer is connected to receive the response of the sample and to output in-phase and quadrature components of the response of the sample. A computer then determines the relevant response characteristics from the in-phase and quadrature components.
