ABSTRACT:
To detect a turbid contaminant in a moving container, radiant energy having a wavelength that is absorbed by contents of the moving container that include the turbid contaminant at a different level than energy having the wavelength is absorbed by contents of the moving container that include a non-contaminant is directed into the container. Thereafter, a level of radiant energy scattered by contents of the container is detected. The presence of a turbid contaminant is indicated when the detected level of scattered radiant energy differs from a threshold level.
