Simulation of Laser Atmospheric Transmission in Laboratory
The simulation of laser atmospheric transmission in laboratory has proceeded upon liquid crystal spatial light modulator. Zernike polynomial was used to produce static atmospheric turbulence phase screen based on isotropic Kolmogorov turbulence model. r0=0.1 m and r0=0.05 m are the atmospheric coherent length under the different turbulence intensity. Dynamic turbulence screen was based on the turbulence freezing method and was loaded in the driver of LC-SLM. Logarithmic intensity probability density distribution at the receiving terminal is close to normal distribution, the determinal coefficients is above 0.9. Arrival angle fluctuation variance is σ1=7.1μrad and σ2=7.49μrad, and the spot concentrated within 2 pixels. The results are consistent with the actual field and have achieved good effect in laboratory.
