The shot noise and thermal noise with homodyne demodulation technique is given in this article. And phase noise induced with different timedelay is also analyzed.
给出了采用零差解调技术时干涉系统的散粒噪声和热噪声,并且分析了在不同时间延迟情况下的相位噪声。

The zigzag waveform movement curve is often used in the scanning mirror of thermal imager, so its performance and frequency are limited by the delaytime of returning movement.
热像仪扫描摆镜通常采用锯齿波形运动曲线,扫描频率和效率取决于回扫间隔时间。

Large delay systems in the control process are very common and difficult to control, such as the majority thermal objects in the coal-fired power plant are with a large timedelay.
