Optical Distributed Sensor Interrogator

The ODiSI is a 21st century strain and temperature measurement system specifically designed to address the test challenges of 21st century advanced materials and systems.
The ODiSI provides more than 1000 strain or temperature measurements per meter of a single high definition fiber sensor. The high definition data can fully map the contour of strain or temperature for a structure under test.
The sensor is flexible, low profile, requires no electrical source, and can be bonded to sharply curved surfaces, embedded within structures, or mounted directly to electrical surfaces.

KEY FEATURES
• Multichannel measurements of strain -
   multiplex up to 200,000 measurement
   locations
• Flexible, lightweight and easy to install
   sensors reduce time to first measurement
• Passive, corrosion resistant, dielectric,
   flexible sensors go where other sensors
   can’t - in bends, around corners,
   embedded inside materials
• Long sensor life - no drift or recalibration
   required, cycle counts >107
• Large strain range and high resolution
   allow for mapping of complex strain
   fields and large strain gradients

APPLICATIONS
• Characterize strain on/in new materials
   and complex structures
• Profile temperature in-situ to maximize
   the efficiency of critical processes
• Measure two- and three-dimensional
   strain fields to validate FE models
• Evaluate multi-material joining
• Embed sensors within materials to
   create “smart parts”
