Abstract
To detect a contaminant in a moving container, radiant energy is directed into the moving container. Thereafter, a level of radiant energy scattered by contents of the moving container is detected. The presence of a contaminant is indicated when the detected level of scattered radiant energy differs from a threshold level. Scattered radiant energy detected by the system includes that scattered by turbid materials within the container and that scattered by foam within the container. Detection of turbid materials or foam may be combined with spectral contaminant detection.
