ODiSI 7100 Distributed Fiber Optic Sensing System
The ODiSI 7100 (Optical Distributed Sensor Interrogator) from Luna Innovations is a high-resolution distributed fiber optic sensing system based on Optical Frequency Domain Reflectometry (OFDR). It is designed for real-time strain and temperature monitoring in laboratory testing, structural health monitoring, materials characterization, and geomechanics applications. The system provides continuous measurements along the entire length of an optical fiber sensor with sub-millimeter spatial resolution.
