The estimation of error in selection of orthogonal basis used for elliptical coefficient measurement

The analysis of sensitivity coefficients to the errors in the measurement of ellipticity coefficients in the devices which decompose electromagnetic wave in linear as well as in circular polarization basis is provided in the present article. The original ratios, which characterize sensitivity coefficient to changing of /spl Delta/r, /spl Delta/m, /spl Delta/y, /spl Delta//spl psi/ in the linear basis and /spl Delta/r in the circular polarisation basis, have been obtained.
