Abstract
A drug screening system and methods of using the same are disclosed. The drug screening system identifies and highlights drugs or other contraband substances enclosed within mailpieces based on score imagery computed from selected wavelengths based on chemical signatures. A wide-field, multispectral short-wave infrared imaging system allows for dissolved, concealed drug screening of mailpieces that improve inspection efficiency and accuracy.
