| Abstract: | Several methods to measure optical turbulence, including their applicable conditions and main problems are briefly reviewed and analyzed. The idea of using fiber sensing technology in atmospheric optie turbulence measurement is introduced, and two valuable technical schemes, fiber interference and fiber collimation and coupling, are given. Experiments showed that distinct turbulence induced signal can be aequired in 2 cm and 10 cm air path by the two methods respectively. Meanwhile, it is found that noise and stability in fiber optic system are the main problems to restrict further study. |
