Abstract
A novel fiber optical turbulence sensing system based on phase generated carrier technique is developed for measuring the intensity and structure of local atmospheric optical turbulence. The turbulence-induced air refractive index fluctuations are detected through fiber optical turbulence sensor array and demodulated by the algorithm of correlation. The system’s dynamic range is 10-18 ~ 10-12, which satisfies most of the sceneries in the boundary atmosphere. Time series of the measured refractive index fluctuations and its power spectrum up to the frequency of 500Hz in different conditions such as sealed box or free turbulent atmosphere are illuminated and analyzed. In the end, some of its applications are briefly outlined.
