Applications of Optical Fiber Sensors to Seismic Precursor Observation of Hydro-geochemistry and Its Prospects

When seismological science enters its middle age and faces challenges, innovation and progress of observation techniques may be one way of the shining forth of its youthfulness. Optical fiber sensors have a lot of advantages, such as intrinsic safety, and good electric insulation, easy of linking into web, easy to realize remote and online measurements and so on. At present optical fiber sensors can completely resolve the difficulties which are met in the digital observation of hydro geochemistry and active fault supervision,and can provide more accurate and reliable data. As optical fiber are used, it is possible to realize remote and deep underground measurements, and also one optical fiber system can be reused by several items at the same time. Optical fiber sensors have a broad prospect of applicantion.
