Vector Singularities Analysis by the Computer Differential Polarimeter

摘要

Laser beam after passing through crystal or fiber-optical elements gains a sharply inhomogeneous field distribution in its cross-section. The polarization structure of the radiation contains a number of singular points that form a skeleton of the given field. In the paper the main principles of construction and functioning of the computer differential polarimeter for analysis of these singular points are considered both experimental and theoretical aspects.
