Abstract

The deformation loss formula for an optical fiber ring is derived from the deformation curve equation of the fiber ring under the action of large radial displacements. Theoretical and experimental results show that such a new type of sensor is highly sensitive to displacement (sensitivity approximately 1 micrometers ) within a wider measuring range (better than 1 mm) which is ten times more than that of a microbending fiber sensor.
