The nonlinearity of heterodyne interferometers is caused mainly by polarization ellipticity or nonorthogonality of the laser beams. Even perfect optical components can also contribute to this nonlinearity. Furthermore, the misalignment of the interferometer seriously affects the nonlinearity of a heterodyne interferometer.
