Phase Mask technology
Benefits
• FBG is small in size and light in weight
• Long operating life, immune to radiation
• Ideal for remote and distributed sensing
• FBG sensor is passive, draws 0 power
• Immune to RFI and EMI
• Can work in hostile environment, like
extreme temperature

Distributed temperature and low
frequency vibration measurement
• Use of FDM technology
• The interrogation unit is a separate
subsystem
• Sensing elements consist of an FBG array
each element has an identical center
wavelength
• The array can be up to 200 elements each
Each sensor box contains 2 fiber coils
