有没有用过偏振分析仪的？
有的话希望能够传一些资料看一下，谢谢！

我很少用：
偏振分析仪.偏振态分析仪
SA2000
FiberPro的偏振分析仪SA2000,可以提供偏振相关分析,包括偏振态(SOP),偏振度(DOP),偏振消光比(PERref,LPER),以及输入光的偏振椭圆倾角。
SA2000在PMD测量和偏振设备维护描述和制作等方面提供多方面应用。一些PMD测量方法,如Jones矩阵固有分析法,扫描主要偏振态法和根据ITU-T G.650要求SOP测量的3 Stokes参数波长扫描法.SA2000可以使用精度为0.6度的邦加球演示来分辨出SOP。
SA2000在0~50dB的动态范围内测量偏振消光比(PER)。PER是偏振维护光纤,PM跳线和PM其他零附件的本质特征。有许多光学设备是与PMF相连的,例如激光器,起偏器,偏振分路器,调节器等。SOP和PER的测量能够有效地矫正以上仪器的偏振轴。

应用领域： 1、偏振分析Polarization Analysis
SA2000测量偏振态和偏振度，同时可以通过软件显示椭圆偏振，邦加球和测试图表等测试结果。SA2000 measures the State Of Polarization (SOP) and Degree Of Polarization (DOP) of optical light. Accompanying software shows the measured results in various types, polarization ellipse, Poincare sphere and graphs.
2.消光比测试 Extinction Ratio Measurement SA2000可以测试消光比(PER)，生产研发保偏光纤的重要特性。保偏光纤跳线和其它的保偏光纤的零附件。它可以测试两种PER值，线性消光比(LPER)和线性参考的消光比(PERref)。同时可以通过软件给出干扰保偏光纤的偏振态轨迹的方法测试消光比的方法。SA2000 measures Polarization Extinction Ratio (PER), which is an important characteristic of Polarization Maintaining Fiber (PMF), PM patch cord and other PM devices. It has two kinds of PER, linear polarization extinction ratio (LPER) and PER to linear reference polarization(PERref). Accompanying software also gives another PER measurement method from the SOP trace of perturbed PM fiber ).
3. 光学偏振轴的对准Alignment of Polarization Axis of Optical Device 对于偏振态和消光比的测试可以用来将保偏光纤和偏振轴对接，比如保偏光纤尾纤到激光器，起偏器，偏振分路器和复合器等等。通过三个用户自定义的模拟输出，可达到非常有效的对准控制。SOP and PER measurement can be used in launching optical light to Polarization Maintaining Fiber and aligning polarization axis of optical devices, such as polarization maintaining fiber pig-tailing to laser diode, polarizer, polarization splitter and combiner, etc.

Active feedback control in aligning polarization axis is possible using three user-configurable analog outputs.
4. 偏振模色散测量PMD Measurements SA2000通过扫描偏振态的方法（3stock的参考波长扫描法）来进行PMD测试，也可通过加上偏振控制器，采用Jones矩阵固有分析法测试PMD。SA2000 can be used in PMD measurement using scanning principal state of polarization methods, 3 Stokes parameter wavelength scanning method ) and also Jones Matrix Eigen Analysis method with the help of the polarization controller ). (ITU-T G.650).
