Abstract

A joint effect of the non-Kolmogorov stratospheric and Kolmogorov tropospheric turbulence on star image motion is studied, and the theoretical predictions are compared with measured data. It is shown that for a large telescope the stratosphere can produce a considerable effect on star image motion. The stratospheric component of a wavefront tilt, similar to the tropospheric one, is wavelength independent, and that permits us to sense the tilt at visible wavelengths for compensation at near infrared wavelengths. The techniques which permit us to single out the contribution of the stratosphere to star image motion, and to exclude the effect of uncontrolled telescope motion on the measured data are described. An analysis of the stratospheric effect on the phase fluctuations power spectrum of a starlight is performed, and it is shown that this effect possibly should be taken into account for interpretation of the interferometric stellar data.
