Problems in the use of laser guide stars

摘要

Some problems, connected with the development of ground- based adaptive telescope, particularly, with equipping it with an additional optical system for laser guide star formation, are treated in the paper. The point of the work is determination of the type of the laser guide star being formed. Here, the calculated results are presented for scheme for laser guide star formation, when arbitrary magnitudes of the correlation between random angular displacements of the image of the scattering volume stipulated by the laser beam fluctuations over direct and back paths can be obtained. Expressions for the monostatic and bistatic schemes are obtained as limiting cases.
