Allowance for quantum noise in adaptive focusing of optical radiation

V. A. Loginov, V. E. Antsiperov


Abstract: An analysis is made of the problem of adaptive focusing of optical radiation on a point-like object across a turbulent atmosphere. The Bayes approach is used to obtain an algorithm for the control of the average tilt of the wavefront on the transmitting aperture. The control is performed using a priori information on the atmosphere and on the coordinates of the object, as well as information on the radiation emitted by the object which is assumed to be luminous. A study is made of the influence of quantum noise in the signal recording process on the quality of adaptation.
