PCU - FSI Interrogator

PCU - FSI Interrogator
Key Features
  • 205 kHz Sampling Frequency
  • 20 nε Resolution
  • 80 Sensing Segments
  • 10 mm - 20 m Spatial Resolution
The Photonic Control Unit (PCU) GEN I is the first commercial interrogator for dynamic measurement of FSI sensors (Fiber Segment Interferometry). This interferometric instrument offers high resolution or deformation and temperature measurements over discrete and distributed sensing lengths. The ultra-high sampling frequency allows for acoustic, vibration and modal analysis. Compatible with 3D shape sensors.
