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.
