Phase Distortions

The reconstruction of a wave front containing random phase distortions of the light field is considered. The reconstruction is performed by a Hartmann method based on the approximation of the wave function by Zernike polynomials using estimates of local slopes. The slope values depend on the algorithms by which they are determined. The number of slopes is proportional to the number of focal spots recorded in the plane of the receiving device, which varies depending not only on the raster dimension, but also on the parameters of turbulence, design features of the receiving devices, as well as being restricted by the orthogonality of Zernike polynomials. Results of numerical experiments are given, which will be taken into account when creating adaptive optics systems for correcting strong turbulent distortions of the optical radiation.

In this paper experiments on laser cooling, collimation and manipulation of a sodium atomic beam, such as the transverse collimation and decollimation of an atomic beam by a standing wave or a misaligned standing wave, longitudinal cooling of an atomic beam by a diffuse light field, sub-Doppler cooling in a blue detuned standing wave, are reported. The basic concept on atom optics is developed. An experiment on a method for the injection of atoms into an atomic cavity is also discussed.
