This book builds on the foundation laid by Optical Fiber Sensor Technology, Volumes I and II. In those volumes the material covered encompassed the fundamentals and underlying principles of the subject and the progress in devices and their associated technology which has taken place in recent years. Optical Fiber Sensor Technology, Volume III concentrates on the applications of the technology and systems that rely upon it with a particular emphasis upon physical sensors. Edited by two scientists with a wide knowledge of the field and the community, the book brings together leading academics and practitioners in a comprehensive and incisive treatment of the subject. This is an essential reference both for researchers working and teaching in optical fiber sensor technology and for industrial users who need to be aware of current developments in optical fiber sensor devices and new areas of the associated technology.

Moisture is critical to the weathering of stone buildings and almost all weathering processes in building stones are influenced by the presence of moisture--especially the cyclic process of repeated ingress and egress of moisture that promotes their decay. Therefore, monitoring the moisture distribution in building stones is essential in understanding the material behaviour and degradation mechanisms associated with stone decay. In this study two real-time monitoring systems, viz. fiber optic sensor probe for relative humidity and electrical resistance sensors are compared by placing them, together with commercially available thermistors and humidity probe, at different depths in a limestone block in order to characterise patterns of moisture and temperature changes with depth from the exposure surface. This surface was then exposed to simulated wetting by a water spray, short-term cycles of heating and cooling beneath an infrared lamp to mimic solar radiation, and an intermittent air flow across the surface of the block. The experiment was conducted within an environmental chamber that kept ambient air temperature at 20°C. Results indicate that variations in external environmental factors, such as wind and intermittent heating cycles, can significantly affect the temperature and moisture variations in building stones.
