Based on the temporal covariance of logarithmic amplitude, analytical expression was obtained for power spectrum of atmospheric scintillation with aperture receiving in the weak fluctuation regime. The effect of the receiving aperture on the power spectrum of atmospheric scintillation was analyzed, the experiment of laser propagation through atmosphere was accomplished and the real power spectrum of atmospheric scintillation was obtained. The theoretical analysis accords well with experiment results. These results show that the power spectrum of atmospheric scintillation with aperture receiving includes low-frequency spectrum and high-frequency components. The amplitude of the low-frequency spectrum is constant. The high-frequency spectrum obeys the power law with an exponent of -11/3. Whe
