Phase-Shifted Gratings
Phase-shifted grating is a technological breakthrough from QPS Photronics since late 2013, achieving 100 times higher performance compared to standard single FBG. Its narrowband transmission peak fits well to applications such as measuring high frequency acoustic emissions or capturing ultra small temperature/strain changes.
Key Features

  •  100 times better performance than regular FBG
  •  50 dB signal-to-noise
Applications

  •  Leak detection in fuel tank 
  •  Acoustic Emission 
  •  Leak detection in pipeline
  •  Delamination in carbon fiber composite panels in aircrafts
  •  PD detection in transformers and generators
