Abstract
These experiments were motivated by the search for an answer to the question about the possibility of effective use of incoherent source as reference one. In the experiments were compared to fluctuations in the image shake for coherent radiation source and for an extended incoherent. Simultaneous measurements of the wave-front aberrations in the urban atmospheric turbulence on the horizontal track length of 104 meters at a height of 10 m above the underlying surface were carried out. In result we suggest a new operational scheme of an adaptive optical system, which does not require a reference source to be specially created or formed. The experimental scheme uses tracing the image of an object, selfluminous or illuminated by external sources. The results show a high correlation between the fluctuations of components of the mode decomposition for coherent radiation, and for the incoherent extended source of radiation. This means that a non-coherent source can be used effectively as a reference in a number of applications.
