Abstract

This paper presents the basic theoretical equations needed for the measurement of turbulence characteristics from observations of the jitter of astronomic images from onboard a flying aircraft. The method allows us to record the integral turbulence intensity (integral of the structure characteristic of refractive index fluctuations C²_n along the optical path). The variance of the jitter of astronomic images is a measured characteristic. This characteristic is thoroughly studied and stable to measurement errors. Two optical detectors: monostatic and bistatic differential ones, were used as recording devices.
