ODiSI-B User's Guide Version 5.2.1
●Luna Innovations’Optical Distributed Sensor Interrogator (ODiSI-B) uses swept-wavelength coherent interferometry to measure temperature and strain using optical fiber as the sensor. The ODiSI-B offers the ability to test a structure at numerous specific points of interest over an extended area.
●Optical fibers undergo well defined physical changes as a result of changes in temperature and strain. The ODiSI-B is therefore, at any given time, able to measure the strain or temperature throughout the length of the fiber, at intervals a slow as 0.64mm. By comparing measurements made at two different times the ODiSI-B calculates and displays the change in strain or temperature.
●The ODiSI-B utilizes fiber optic sensors ranging from 1m to 20m in length to make distributed strain and temperature measurements of a test article. Due to the small diameter of the fiber (<0.2mm), the fiber can be routed into locations not usually possible with foil gages and thermocouples. The ODiSI-B has the ability to differentiate the sensing fiber from other fiber optic devices (patch cables, switches, etc.) and is therefore able to be reconfigured without a change in measurement data.
