Numerical method for modeling nonspherical aerosol modulation transfer functions

Aerosol scattering produces image degradation effects which can be characterized by the MTF. This paper describes a technique for calculating MTFs for atmospheres containing nonspherical particles. The approach uses the extended boundary condition method and a Monte Carlo simulation to model a scattering atmosphere. Model MTF results for 8.0 and 9.2 microns are presented for media containing spheroidal particles.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
