ABSTRACT:
A method for approximating dynamic effects of atmospheric turbulence on infrared digital imagery utilizing the application of at least one spatially varying system to an object intensity distribution to obtain at least one image intensity distribution. The spatially varying system represents atmospheric turbulence which varies phase and/or amplitude as a function of a spatial index. The object intensity distribution and the image intensity distribution are related by an image warping transformation. Two configurations for experimental verification of the utility of a turbulence simulation technique are also disclosed.
