Abstract

There has been a lot of interest in the use of optical fiber sensors in the monitoring of the structural health and dynamics in wood based structures [7]. In particular there has been a need for the implementation of optical fiber sensing probes in trees, for monitoring their growth dynamics (Dendrometry) versus weather conditions and agricultural practices (watering, fertilization, etc). Also, there is practical and industrial interest in the implementation of optical fiber sensors in wood based structures for accessing their structural health versus weather and environmental conditions, especially that of humidity and exposure to water. In this thesis we are performing preliminary investigations on the development of optical sensing probes based on optical fiber Bragg gratings, with potential applications in Dendrometry and wood structures assessment. Two sensing configurations are examined: a flexible belt made of PDMS containing a FBG for potential application in dendrometric applications (see Figure 2-2); and a ring- attached FBG for application in the monitoring of the expansion dynamics due to water exposure of cylindrical wood structures.
