Continuous Monitoring of Wooden Works of Art using Fiber Bragg Grating Sensors

The aim of this research is to evaluate the applicability of optical fiber sensors to the field of art, particularly to the monitoring of painted wood panels exhibited in different environmental conditions or during restoration processes. The wood support is an essential element of the works of art and is highly sensitive to the environmental climate modification. Wood deformations may have irreversible destructive effects on the work of art. The use of fiber Bragg grating (FBG) sensors for the quasi-distributed in-situ measurement and continuous monitoring of the painted wood panel deformations is proposed. FBG sensors have high resolution low invasivity and intrinsic safety.
