Experimental Principle of Fiber Optic Strain Sensor
Fiber optic strain sensors typically function by interpreting changes in light properties as strain is applied. In this paper, accuracy calibration experiments and the related analyses of two fiber-optic sensing technologies, the fiber-optic grating (FBG) and optical frequency domain reflectometry (OFDR), are carried out using a standard beam of equal strength and a mature resistive strain gauge (ESG). Fiber-Bragg-Gratings (FBGs) are used for spot sensing, whereas Rayleigh, Brillouin and Raman scattering are used for distributed sensing in long fibers. A major challenge in the field is to analyze and predict the strain transfer to the fiber core reliably.

The os3100 is a spot-welded or epoxy-mounted optical strain gage based on fiber Bragg grating (FBG) technology. Its stainless steel carrier holds the FBG in tension, using no epoxy. What are Optical Strain Sensors? Optical strain sensors (or strain gauges) are sensors for compressive and/or tensile mechanical strain (deformation) which are based on optical technology — in most cases, on fiber optics. They are easy to install, immune to electromagnetic interferences and can also be used in highly explosive atmospheres.
