Abstract

While propagating in the turbulence atmosphere a laser beam experiences considerable distortions of the wave front, which lead to essential limitations of potentiality of data transmission laser systems and laser radars or to worsening of optical telescopes resolution. Well-known methods of adaptive optics permit us to compensate atmosphere influence and telescope aberrations and to get a diffraction-limited laser beam. However, these methods are designed for work with point objects. They are not effective if the size of an object is more than several resolution elements. The space-information structure of the reflected field is analyzed and on the basis of its properties analysis criteria (methods) of adaptive forming of a diffraction limited beam on the surface of a long object are proposed.
