Distributed Polarisation Crosstalk Analyser - PolaX™
The Distributed Polarisation Crosstalk (X-Talk) Analyser (PXA-1000) is an enhanced version of a white light interferometer designed to obtain space-resolved stress information by analysing stress-induced polarisation cross-coupling along a length of polarisation maintaining (PM) fibreFeatures
- High spatial resolution: 6 cm
- PM fibre as intrinsic sensing element
- -80 dB polarisation X-talk sensitivity
- 30 dB PER measurement range
- Large fibre measurement range: 2.6 km
Applications
- Distributed stress sensing
- Structural change monitoring in bridges, tunnels, dams, and buildings
- PM fibre quality inspection
- PM fibre coil winding in-process monitoring
- PM fibre coil quality inspection
- Quality inspection of polarising wave guides
- Intrusion detection
