In-Line Polarization Analyzer

Product Summary
The POD-101A is an in-line polarimeter specially designed for high-speed polarization analysis and monitoring.
The instrument uses four channels to simultaneously obtain the four Stokes parameters and measure the instantaneous
state of polarization (SOP) and degree of polarization (DOP) of an input light beam. A simple USB interface enables data
to be transferred directly to a computer without the need for any additional hardware. With a sampling rate of up to 48 KS/s,
this polarimeter easily monitors and analyzes fast polarization changes. The POD-101A comes with PolaView™ software for real-time
graphic display of polarization state either on a Poincaré Sphere window for viewing SOP traces or on an oscilloscope window
for tracking polarization changes over time. The oscilloscope window has three operation modes: continuous scan mode,
for instantaneous display of various polarization parameters; external trigger mode, for capturing transient events;
and long term monitoring mode, for recording only the polarization changes above a predetermined threshold,
in order to save hard drive space. The POD-101A is ideal for PMD compensation, polarization stabilization,
system polarization monitoring, polarization analysis, and sensor analysis.
