Mitigation of Atmospheric Effects on Imaging Systems
Abstract
Atmospheric effects such as refractive turbulence and aerosol obscuration can seriously degrade the performance of military optical systems. A complete understanding of these effects is therefore essential for optimizing the design of such systems, and it is also necessary for developing mitigation techniques. The project described here was a three-year theoretical and experimental investigation to develop and validate a physical understanding of several atmospheric effects that are important for current and future Army optical systems. a) An investigation of turbulence-induced waviness in images of edges, and techniques for its mitigation. b) An investigation of the degradation of optical images by atmospheric turbulence and a validation of the predicted dependence of the atmospheric Modulation Transfer Function (MTF) on the inner scale of turbulence.
