Optical fibers are materials that have been known for decades. Although the implementation of this technology was directly related to the telecommunications industry and is largely associated with this field, optical fibers have also been used as sensors for a long time. The wide applicability of optical fiber sensors (OFSs) for temperature, strain, displacement, pressure or acceleration measurements allows us to think of OFS as a technology of our future. From the point of view of civil engineering, one of the most interesting applications of optical fiber sensing is the use of this technology to monitor elements of building structures, communication infrastructure or underground utilities. Observing the dynamic development of theoretical, numerical and practical applications of optical fiber sensors in the field of civil engineering, I would like to invite you to submit your manuscripts to upcoming Special Issue “Optical Fiber Sensor Measurements in Civil Engineering”.
