Paper Abstract

The paper describes a method of calculating the point spread and modulation transfer functions for imaging through aerosol media. The method is based on the image solution of a point source determined with the multiscattering propagation model of Bissonnette (1988). Results are presented that illustrate the effects of particle size, extinction coefficient and geometry. Comparisons with measurements show good consistency but no systematic validation is performed because the available image and aerosol data are not sufficiently documented or outside the range of validity of the propagation model. The calculated modulation transfer functions are applicable to image enhancement algorithms and could potentially be inverted to provide information on particle sizes.
