ABSTRACT:
A contaminant detection system includes a transmitter for transmitting a guided wave through the skin at particular resonances, wherein each resonance point utilized will have propagation characteristics sensitive to a condition of interest. A contaminant may then be classified by transmitting several resonances and then carrying out appropriate feature extraction and pattern recognition techniques utilizing a host processor.
