In order to improve the frequency stabilization of the Doppler modulator,a series of affecting factors are considered in depth and optimized in the aspects of optics,mechanics and electronics.The experiment results show that:the frequency stabilization of the optimized Doppler modulator has already reached RMS error about ±1%,which could meet the need of reference signal of the lock-in amplifier.
