[0008] In another example, a method is described to include directing light from a light source through an optical bandpass filter to produce a reference light beam; measuring a first degree of polarization of the reference light beam output from the optical bandpass filter; and using the first degree of polarization to compute a first optical signal to noise ratio. This method also includes directing the light from the light source through an optical amplifier first and then through the optical bandpass filter; and measuring a second degree of polarization of light output from the optical bandpass filter; using the second degree of polarization to compute a second optical signal to noise ratio. This method further includes using the first degree of polarization and the second degree of polarization to determine a noise figure of the optical amplifier.
有关偏振控制方面的

再介绍一种方法:
1.从光源发射的直接光束通过一个带通滤光器,产生一束相关线偏振光束。测量相关线偏振光束从带通滤光器输出的初始偏振角,并且用初始偏振角估算最初的光学信噪比。
2.先引导光源发出的光线到一个光学放大器,然后在通过带通滤光器,用第二个偏振角估算第二光学信噪比。
3.综合两个偏振角来测定光学放大器的噪声系数。

不是本专业的,看能不能帮上你。

科技文章貌似

在其它例子, 方法被描述包括指挥光从一光源

举一例子,一种方法为一束直光从铈光源发出头国滤波器生成相应光束;测量从滤波器中射出的光束之第一波段的偏振量,并利用的出的测量数值计算出光束的信躁比。同样的,可以让从直接光源中的光线首先通过光学放大器,随后通过光波滤镜,得以测量出两极的第二波段值。据此得出第二波段信躁比。
此方法可以进一步认定为采用第一和第二波段值来确定光学放大器的信躁比。
