Summary:Based on the Jones matrix formalism, the paper describes the optical scheme of a single-pass homodyne displacement measuring interferometer with a quadrature principle of phase detection. The interferometer is based on the Michelson scheme, and quadrature signals are obtain using polarization optical elements. The interferometer is supposed to be used as part of a new domestic kilogram standard based on watt-balance for precision measurements of the vertical displacements and speed of the coil. The results of modeling the optical scheme of the interferometer in order to assess the influence of the imperfection of polarization elements on the accuracy of measurements and the quality of their alignment are considered. An algorithm for compensating for nonlinear effects arising from quadratic detection of interference signals is also implemented.
