演示了一种锁定相对相位以在来自一对相位调制器的相位调制边带之间提供稳定的相长或相消干涉的方法。从理论上讨论了与故障系统的相位噪声相关的最佳条纹可见度。采用相位调制和锁定技术进行锁相后，相对相位漂移集中在+-0.0016 rad左右，条纹可见度限制在2×10?4。
A method of locking the relative phase to provide stable constructive or destructive interference between the phase-modulated sidebands from a pair of phase modulators is demonstrated. It is discussed theoretically for optimal fringe visibility related to the phase noise from faulty system. After phase locking using the phase modulating and lock-in technique, the drift of the relative phase is focalized around +-0.0016 rad and the fringe visibility is restricted to 2×10?4.
