Abstract

When laser propagation through atmospheric turbulence, the effect of anisoplanatic error will affect the compensation results of adaptive optics system. Based on the wave optics propagation model, laser propagation through horizontal path atmospheric turbulence with AO compensating simulation system was established to study the anisoplanatic error in turbulence with diffraction effect. Propagation experiments through a 4-km horizontal path outside were conducted. The AO compensating effects in different isoplanatic angles were tested at different turbulence strength. Both simulation results and experimental data show that during the isoplanatic angle with influence of piston and tilt terms removing the AO system possess effective compensation results.
