ABSTRACT:
A contamination detector in accordance with one embodiment of the invention includes a plasma generation system operable to direct an atmospheric plasma discharge towards a surface. The contamination detector further includes a light capture system to capture light generated by interaction of the atmospheric plasma discharge with the surface. The light capture system guides the captured light to an optical detection system configured to detect a contaminant.
