Abstract
A flexible atmospheric turbulence simulator based on spatial light modulator is investigated experimentally. Phase screens generated by Fourier Transform method are used in the proposed scheme. The effect of time-varying atmospheric turbulence with different strength is successfully demonstrated. The far-field intensity and received optical power of Gauss-shaped laser beam under relatively weak, moderate and strong atmospheric turbulence are measured. Experiments show that atmospheric turbulence will cause the distortion of far-field intensity distribution and fluctuation of received optical power.
