Adaptive System for the Formation of Laser Beams in the Atmosphere by Use of Incoherent Images as Reference Sources

摘要

Adaptive focusing of a coherent beam of radiation in a turbulent atmosphere is considered. The average intensity distribution of the field of a coherent laser beam focused in a turbulent medium upon adaptive phase correction using the image of an incoherent source as a reference source has been calculated. The measurement data on image jitter of an incoherent source are shown to be applicable in the adaptive focusing of a coherent radiation beam. Phase measurements in such a scheme can be implemented by the Hartmann correlation sensor.
