ABSTRACT:
An apparatus and method for performing ultrasonic spectroscopy provides for rapid evaluation of test materials with good amplitude, balanced response at all test frequencies. A swept frequency signal is generated which is applied to a transmit transducer coupled to a test part. A receive transducer provides a detected signal that is fully digitized for real-time or post signal processing. The created swept frequency signal can be equalized from data obtained from direct coupling between transmit and receive transducers. The resultant data is analyzed for amplitude and/or phase information as a function of frequency and can be used to analyze filter characteristics, identify resonances, characterize material signatures and many other applications.
