Two-Dimensional Phase-Screen Models

Simplified models that capture the essential elements of physical phenomena are used extensively.  The equivalent phase-screen model is a case in point, but the approximation is not overly constraining.  As as long as the structure encountered is statistically uniform or … Continue reading

Phase Screen Models for Numerical Computation

To the extent that propagation disturbances can be approximated by an equivalent phase-screen, there are analytic models that allow computation of the power-spectrum of the intensity of the field as it propagates away from the phase screen.  The analysis involves … Continue reading
