Abstract

We show how to simulate realistic turbulent imagery using only two scalar fields, from which we derive a Gaussian and non-isoplanatic Point-Spread Function (PSF). The first field controls mainly scintillation effects, while the second principally controls image displacements. The model is designed for weak turbulence and is based on the first-order Rytov theory for propagation through turbulence. We explain the physical principles behind the model and justify them using empirical evidence.
