Numerical Study of Dynamic Adaptive Phase Correction of Radiation Turbulent Distortions and Estimation of their Frequency Bandwidth with a Shack–Hartmann Wavefront Sensor

The effect of limited operation speed of an adaptive optics system with a Shack–Hartmann wavefront sensor (WFS) on the efficiency of correction of dynamic laser beam phase distortions due to atmospheric turbulence is numerically studied. We suggest estimating the frequency bandwidth of significant t...

Zusammenfassung:The effect of limited operation speed of an adaptive optics system with a Shack–Hartmann wavefront sensor (WFS) on the efficiency of correction of dynamic laser beam phase distortions due to atmospheric turbulence is numerically studied. We suggest estimating the frequency bandwidth of significant turbulent distortions with a WFS, which is convenient from a practical point of view.
