Research Institution
The computational burden of simulating the process of imaging incoherently illuminated extended objects, through high turbulence, using conventional wave optics simulation techniques is very significant. This simulation capability is crucial for evaluating performance of such systems as the Advanced Tactical Laser (ATL). An innovative approach to this problem, that will significantly reduce the computational requirements, is proposed. The approach is based on a very fast technique for propagating point spread functions. A key feature of the approach is the capability of propagating in both directions, that is, imaging a target through turbulence and propagating a source back to the target which experiences the same turbulence as the imaging direction. This allows the simulation of closed loop laser projection systems. In spite of simplifications introduced to reduce computational requirements, the approach has the potential of a high level of imaging fidelity, even in severe turbulence.
