Abstract:

The Kolmogorov spectrum for the refractive index is often assumed for analysis and simulation of optical propagation through turbulence. It is recognized that the Hill spectrum, including inner scale, is a more realistic model of index variations. This model includes a turbulence enhancement in a spectral subrange prior to the inner scale roll-off. Knowledge of this enhancement and the subsequent roll-off is important for predicting the statistics of both phase and scintillation effects. A technique for estimating the inner scale, L0, is proposed which can be implemented as part of a simple sensor system. The proposed inner scale sensor is also capable of estimating the Fried coherence length, r0, and the Greenwood frequency.
