Polymer optical fiber (POF) sensors based on the Optical Time Domain Reflectometry (OTDR) technique provide the unique ability to measure high strain up to 40 % fully distributed along the fiber. Standard PMMA POF are introduced and evaluated in potential use and applicability. The advances in distributed POF strain sensor technology are concluded with respect to application in structural healt...
