Abstract

Abstract

Random fluctuation of turbulence brings random fluctuation of refractive index and makes atmosphere become a random fluctuation medium, which destroys the coherence of light-wave. Research of atmospheric turbulence is actually investigation of atmospheric refractive index.The atmospheric structure constant of refractive index is an important parameter of denoting atmospheric turbulence. In this paper, the atmospheric structure constant of refractive index is measured both noonday and at night everyday, at all seasons, respectively,using HTP-2 micro-thermal meter. The vertical profile of refractire index in Hefei and the North（0～30 km）is investigated by analysis of experimental data．
