Description
Polarization analyzer is an instrument for polarization measurement and stability monitoring. It provides comprehensive functions to analyze the polarization characteristics of optical signals, and is used for real-time detection of beam polarization parameters, high-speed analysis and monitoring of polarization states. The polarization extinction ratio of narrow band light can be measured by combining the polarization state heat cycle heater with the measurement technology of heated fiber. Four Stokes parameters are obtained simultaneously using four channels, and the instantaneous polarization state (SOP) and degree of polarization (DOP) of the input beam are measured. Due to sampling:
With rates up to 1MS/s, the instrument is ideal for analyzing interference and fluctuating signals, as well as control applications that require real-time feedback of polarization information, such as digital control loops in automated manufacturing test systems. Using the upper computer software can be displayed in real time
The Bunga sphere, the trajectory of the upper polarization state, or the change of the polarization state over time in the form of an oscilloscope, can display the polarization state (PER) in real time on the Bunga Sphere window. For specific wavelengths and temperatures, it can be quickly calibrated with a built-in self-calibration program to optimize DOP and SOP measurement accuracy.
