A response function for image transmission in a medium containing discrete, isotropic scatterers is derived in a form analogous to the point-spread function of media with continuous variations of refractive index. A primary-scattering approximation is used with a geometry similar to that employed in determining telephotometry error. The analysis is substantiated by means of an experiment involving a dispersion of an acrylic sol in water.

  10. This analysis departs significantly from that employed to determine the total flux entering a telephotometer aperture, wherein a point source of light is assumed.
  11. Total attenuation coefficient α is expressed as α = αa + αs, where αa is that portion of the attenuation coefficient that results from absorption and αs that portion arising from scattering.
