The optical turbulence in atmosphere, especially in the atmospheric boundary layer, plays a important role in the propagation of laser beam. It can make the fluctuation of density and distortion of wave front. The balloon borne radiosonde with temperature fluctuation sensors is often used to study the turbulence profiles in the atmospheric boundary layer. But it can not get the continuous temporal and spatial variance of turbulence structure. In this paper, Doppler sodar and microwave wind profiler are used to study the optical turbulence structure in the atmospheric boundary layer. The fluctuation in the index of refraction can be defined as optical turbulence, so the structure constants of refractive index C-n(2) is often used in such problems. Not only the wind profiler but also the high solution temporal and spatial turbulence structure can be gained with Doppler radar. From these experimental results, we study the relative structure of turbulence on different height, study the spectra of C-n(2) on different. These results are compared previous results get with temperature fluctuation sensors. In addition, the seasonal variance of turbulence structure is also discussed in the paper.
