Zusammenfassung:	A method and apparatus for evaluating the scattering properties of a transparency image comprises projecting radiation through the transparency image to form a transmitted beam of radiation; splitting the transmitted beam of radiation into at least two distinct beams of radiation, a first distinct beam and a second distinct beam; measuring a first amount of energy in the first distinct beam that corresponds to non-scattered light; measuring a second amount of energy in the second distinct beam that corresponds to scattered light; and comparing the first amount of energy to the second amount of energy to determine the proportion of the transmitted beam of radiation that is not scattered.
