Abstract
In this paper, the causes of nonlinearity of a laser interferometer with a single-frequency laser and a detection system with two signals in quadrature are described. Several methods of nonlinearity measurement are presented. Experimentally was tested a method with a linear mechanical shift and a method of linearity measurement using optical resonator. When using linearity compensation by means of a PC program, a deviation from linearity in limits of +/- 0.5 nm for the linear mechanical shift method was achieved. The preliminary results recorded during the linearity measurement with the optical resonator are below the limit of +/- 1.0 nm.
