Based on our previous setup, a signaldifferential module is introduced to reduce the noise rising from the fluctuation of the laser power to improve the quality of the experimental interferogram.
并在原实验装置的基础上，利用信号差分方法减少了光强波动对实验干涉谱图的影响，改善了信噪比。

It solves the problem of modulate and demodulation of differentialsignal and achieve data and power signal communication in coaxial-cable.
该模块解决了对差分信号“调制”、“解调”问题，实现了数据和电源在同轴电缆上的同步传输。

Relations between differential pressure signal and two-phase flow parameters are studied in the dissertation.
