A Non-Kolmogorov turbulence simulation experiment was carried out in the laboratory, based on the liquid crystal spatial light modulator. The probability density distribution, the scintillation index and the temporal powerspectrum were analyzed, and the experimental results were compared with the the turbulence theory. The results show that the probability density distribution of the normalized logarithmic intensity is more close to the normal distribution under weak turbulence, and the fitting coefficient becomes larger with the decrease of the turbulence strength. In the high frequency band of the intensity temporal power spectrum, the power law reduces as the turbulence spectral power law decreases. Although its value is less than the theoretical analysis, the variation trend does match the theory.The scintillation index decreases with the increase of the atmosphere coherence length. It changes abruptly when the atmosphere coherence length is less than 0.05 m, while it tends to change flattenedly when the atmosphere coherence length is greater than 0.2 m. This changing trend remains the same under different Non-Kolmogorov turbulence spectrum, which is also consistent with the theoretical prediction. The results illustrates that the turbulence simulation experiment can reproduce the turbulence effect on the received light intensity in wireless optical communications. Moreover, the error analysis of the simulation experiment illustrates that the main sources of the experimental error are different under different turbulence strength. It can provides some effective advices for the improvement of further experiments.
