Abstract

A fast approximation method for simulating the dynamic effects of atmospheric turbulence on infrared digital imagery is presented. The method is based on the distant phase screen approximation for certain turbulent conditions and is an application of the theoretical work published by M. I. Charnotskii, et al. in 1990. The computational efficiency of the method allows realistic incorporation of the atmospheric turbulence effects in high resolution interactive simulation environments for military and commercial applications. Simulations of turbulence effects on digital infrared images are presented together with actual images obtained from a commercial 8- to 12-micrometers infrared system imaging through thermally induced atmospheric turbulence.
