PXA-1000 Distributed Polarization Crosstalk Analyzer - PolaX™

PublishTime：2022-03-30

●The Distributed Polarization Crosstalk (X-Talk) Analyzer (PXA-1000) is an enhanced version of a white light interferometer designed to obtain space-resolved stress information by analyzing stress-induced polarization cross-coupling along a length of polarization maintaining (PM) fiber. Its patented (US 8,599,385) optical design eliminates the strong zero-order interference and reduces the multi-coupling interference common in traditional white light interferometers, both of which can cause “ghost” peaks in the measured signal. The removal of the “ghost” peaks enables the PXA-1000 to unambiguously identify the magnitudes and locations of actual x-talk peaks, resulting in higher measurement sensitivity, higher dynamic range, and higher spatial measurement accuracy than traditional white light interferometers. The PXA-1000 also enables the use of the PM fiber itself as the sensing medium, eliminating the need to place multiple fiber gratings along the fiber. It can therefore obtain higher spatial resolution of the stress distribution than grating-based systems. Because no discrete sensing elements are required, the system is easy to install and calibrate, making it ideal for monitoring space-resolved structural changes along bridges, tunnels, dams, oil pipes, or buildings. It can also be used as an intrusion detection system, because any mechanical disturbances to the PM fiber will cause polarization coupling. Another important application is PM fiber quality inspection. The PXA-1000 easily identifies defective sections of PM fiber, enabling the manufacturers or users to remove them. Furthermore, the PXA-1000 is ideal for quality inspection and screening of PM fiber coils, since it can pinpoint the locations of imperfections or areas of local stress on the fiber coil induced during the fiber winding process. The PXA-1000 comes with a notebook computer equipped with PolaXView™ software, which displays the location and polarization coupling ratio of each stress point as a function of distance, and identifies stress points with polarization coupling above a user defined threshold level, with a list of the locations and polarization coupling strengths of all stress points. Other applications of the instrument include measuring the extremely high polarization extinction ratio of a polarizing waveguide, obtaining the autocorrelation function of a light source, measuring the length or birefringence of a PM fiber, and matching the optical path lengths of an interferometer.
