英文摘要	a simpler generalized expression of irradiance fluctuation for flat-topped beams is presented based on the born and rytov perturbation methods. the theoretical expression of the on-axis scintillation index in non-kolmogorov weak atmospheric optics links is developed using the generalized von karman spectrum model, and using the equivalent structure constant that is different for all power-law exponents. the effect of the inner scale on the on-axis scintillation index is examined comprehensively. it is observed that flat- topped beams happen to possess smaller scintillation indices at larger inner scale. the effects of the power law, flat-topped order, source size of the fundamental gaussian beam, propagation distance, and wavelength are also analyzed.
