摘要：
This paper describes a method to estimate the differential detection for reducing laser noise in an electro-optic sensor system. This new estimation method evaluates the differential detection effect on noise reduction by using a phasor diagram and fast Fourier transform. The estimation results obtained from this method agree with the DC level dependence of the signal-to-noise ratio, thus confirming that the proposed estimation method is suitable for evaluating the effect of differential detection on noise reduction.
