Statistical optics and effective medium theories of color
Measurements of color are typically made by determining the spectral intensity of light diffusely reflected from images. In xerography color images are heterogeneous systems composed of light absorbing pigments of different colors and sizes suspended in a semitransparent binder. Classical textbook optics predicts the intensity of light specularly reflected from smooth homogeneous surfaces, but cannot provide the detailed information required for these complex optical systems. On October 30, 1992 Robert J. Meyer from Webster Research Center of Xerox has described how statistical optics and effective medium theories predict the intensity of light diffusely reflected from a rough surface of a body containing many small particles; such systems occur within the color image photocopier. He indicated some shortcomings of the dynamic effective medium theory and presented open problems.
