基于初等矩阵的光信号/网络分析仪
摘要：
一种用于描述被测设备的特征的方法包括使多个光信号传播经过被测设备，并且将多个光信号与参考光信号合并。多个光信号被与参考光信号混频，并且来自多个光信号与参考光信号的混频的多个光信号之间的相对扰动被确定。在另一个实施例中，调制后的光信号被从本地振荡器提供，并且调制后的光信号被与输入光信号合并。调制后的光信号被与输入信号混频，以提供混频后的信号，并且输入光信号的至少一个偏振分辨的参数被从混频后的信号中抽取出来。
摘要（英）：

A method for characterizing a device under test 24 includes propagating multiple optical signals 28 through the device under test and combining the multiple optical signals with a reference optical signal 48. The multiple optical signals are mixed with the reference optical signal and a relative perturbation between the multiple optical signals from the mixing of the multiple optical signals with the reference optical signal is determined. In another embodiment a modulated optical signal is provided from a local oscillator 72, Fig. 4, and the modulated optical signal is combined with the input optical signal. The modulated optical signal is mixed with the input signal to provide a mixed signal and at least one polarization-resolved parameter of the input optical signal is extracted from the mixed signal.
