The Effect of Atmospheric Turbulence on Air to Ground Photography.

Abstract

The current state of the theory of optical effects of atmospheric turbulence is summarized, and the derivation of an equation relating the modulation transfer function of an optical path through the atmosphere to a weighted integral of the structure constant of refractive index along that path is outlined. Methods of estimating the structure constant from more readily available meteorological parameters are discussed, and FORTRAN subroutines for evaluating the integral and estimating the modulation transfer function of the path under any required conditions are given.
