Ultrasonic Fingerprints of Materials (103)

Typical Ultrasonic Fingerprint

Problem: Provide definitive method to identify and authenticate individual high-value metal and composite samples

Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Integrated Systems

PNNL Solution:

  • Determined if ultrasonic (UT) "fingerprints" allow reliable sample identification
  • Developed small UT scanner to obtain in-field sample "fingerprints"
  • Developed method and software for automatic "fingerprint" verification
  • Delivered portable "fingerprinting" instruments tailored to client needs
Typical Ultrasonic Fingerprint

Capabilities Employed to Meet Client Needs: Ultrasonic transducer and detector design and fabrication; ultrasonic interaction with materials; mechanical system design including scanner mechanisms; analog and digital electronics design and fabrication; data analysis algorithm development; statistical tests for data analysis; software development for system control and data analysis; system integration; system documentation.
