ABSTRACT:
The present invention pertains to Lithium-Niobate fiber optical sensors (“LNCF”) and systems for detection of load or pressure and strain or deformation changes that occur in a host material. The host material can be a component of a system, such as a part of a bridge, or a selected material, such as a geofoam, that provides a protective and compliant medium to which the LNCF would be securely attached.
