Abstract
Kolmogorov-like atmospheric turbulence is simulated through loading phase screens in sequence onto a liquid crystal on silicon (LCoS) device. Generated phase screens are calculated using power spectrum density method, together with compensation of loss of low frequency by Harmonic method. The computed result of phase structure function shows that after 4 times compensation of Harmonic method, phase screen can simulate Kolmogorov-like atmospheric turbulence accurately. In experiments, a LCoS device manufactured by Holoeye incorporation is calibrated to ensure Precise phase modulation, including inherent wavefront distortion and modulation phase depth. After that, excellent experimental results of dynamic turbulence simulation are demonstrated.
