Abstract:
The simulation results of errors introduced by non-ideal quadrature signals in homodyne interferometers are presented. The empirical formula for uncertainty of uncorrected signals was obtained using the Monte Carlo method (MCM). Generally, the phase error of real uncorrected quadrature signals can be obtained, independently of their physical nature.
