Abstract
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.

A method for evaluating the scattering properties of a toned or inked transparency image comprising:
- projecting radiation through the inked or toned 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 to evaluate the scattering properties of the toned or inked transparency image.
A system for evaluating the scattering properties of a toned or inked transparency image comprising:
- a radiation source that projects radiation through the toned or inked transparency image to form a transmitted beam of radiation;
- a beam splitter that splits the transmitted beam of radiation into at least two distinct beams of radiation, a first distinct beam and a second distinct beam;
- a radiation detector that measures a first amount of energy in the first distinct beam that corresponds to non-scattered light;
- a radiation detector that measures a second amount of energy in the second distinct beam that corresponds to scattered light;
- and
- a processor for 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.
A self-contained unit for evaluating the light scattering properties of a toned or inked transparency image on a support comprising
- a support element for a transparency image on a support layer;
- a radiation source that projects radiation through the toned or inked transparency image to form a transmitted beam of radiation;

- a radiation detector that measures a first amount of energy in the first distinct beam that corresponds to non-scattered light;
- a radiation detector that measures a second amount of energy in the second distinct beam that corresponds to scattered light;
- and
- a processor for 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.
