Abstract

Effects of light propagation in random atmospheric optical turbulence are critical problems for ground based high resolution optical imaging. To get further knowledge of turbulence intensity or structure properties, the concept of fiber optic sensing system is proposed and realized. Different to fine-wire platinum resistance thermometer or laser scintillometer, the system has the ability to make non-contact measurement of optical turbulence up to the frequency of 500Hz during the air gap of 100mm, and has the dynamic range of 10⁻¹⁸ ~ 10⁻¹² . The optic fiber’s merit of corrosion resistance is sufficiently demonstrated by one month field test on the seacoast. Some properties of high frequency turbulence power spectrum that have never been observed before in the range of 10cm are reported. In the end, prospects of optical turbulence research by the usage of fiber optic turbulence sensing system are also discussed.
