Optical Distributed Sensor Interrogator (ODiSI)

ODiSI Product Demonstration

Luna Technologies’ Optical Distributed Sensor Interrogator (ODiSI) instrument enables high resolution temperature and strain measurements using telecom-grade optical fiber as the sensor. The ODiSI offers the ability to test a structure at specific points of interest or continuously along the fiber with user-configurable sensing locations and gage lengths. A single fiber connected to a single, compact instrument provides high definition, unprecedented visibility into your structure under test, providing more information at a fraction of the cost.

Measurements:

• 50 meter maximum sensing length
• 1 mm gage length
• ± 2 μstrain and ± 0.2 °C repeatability with 1-cm gauge length
• ± 15,000 maximum μstrain

Advantages:

• Multiple sensing points with a single connection
• Easily deployed, inexpensive, disposable sensors
• Lightweight and immune to EMI/RF interference
• High definition sensing - 1mm gage length, 400 μm spacing
• Simultaneous strain and temperature measurement with a single fiber sensor
• User-configurable gauge length and sensing locations
• Customize sensing points
• Re-process stored data at a later time with more/different sensing points or higher spatial resolution

Applications:

• Load/fatigue/mechanical testing
• Model and simulation validation
• Design verification and optimization
• Composite manufacturing and engineering
• Structural Health Monitoring
