EM Characterization of Hidden Metals (107)
Problem: Develop non-invasive method to obtain unique signatures of metal objects within closed containers
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Measurement & Analysis System Applications
PNNL Solution:
- Developed electromagnetic (EM) sensing system to examine metal objects inside metal containers
- Low-frequency EM fields penetrated container and interacted with contents
- Sensor impedance measurements distinguished between various possible enclosed metal object(s)
Capabilities Employed to Meet Client Needs: Sensor development based on eddy current sensors; signal processing electronics development; image acquisition and analysis; electromechanical test fixture design and fabrication; test planning and analysis; reporting of results and test methods.
