Image jitter meter for low intensity radiation

Abstract

This development is carried out in the interests of creating a remote optical meter operating on the optical signal of a weak extra-atmospheric source - such as a star. It will allow obtaining data on turbulence for inclined paths at different heights above the underlying surface, and will also make it possible to detect the presence of turbulent layers in the atmosphere, including the presence of non-Kolmogorov turbulence in the atmosphere. For this purpose, it is planned to create two single-channel mock-ups of image jitter meters operating on signals from two different optical sources in a scheme with intersecting lines of sight. Atmospheric experiments have been carried out to compare the results of measurements of atmospheric turbulence by various methods.
