Phase-difference detection based on a double position sensing detector (PSD) configuration for coherent combination is proposed in this paper. The exact phase difference can be extracted from two PSD signals by using an algorithm, which can be used as the driven signal added to the phase modulator for phase-difference compensation. Numerical calculation considering practical experimental conditions was performed to show that the method is of great potential for coherent combination.
