Abstract Details

2021, Doctor of Philosophy (Ph.D.), University of Dayton, Electro-Optics.
Wave optics is used for modeling laser propagation through turbulence, and with laser technology maturation, the simulation space has expanded to the point that current turbulence representations via phase screens are lacking. This research eliminates such deficiencies by adopting a fractal description of turbulence in order to facilitate a noise function based phase screen. Primarily focused on aero-optical data collected using Shack-Hartmann wavefront sensors, novel analysis processes are developed that leverages off of wavelets, circular statistics, optical flow, and radial basis functions. The resulting values serve as inputs for noise function based phase screens generators supported by a dedicated physics based render engine developed from first principles. Finally, multiple wave optics simulations demonstrate the flexibility of this methodology, culminating with an airborne example that includes turret slew over the hemisphere, producing angle dependent far-field irradiance profiles distorted by localized, non-stationary turbulence.
