Paper Abstract

The results of high-performance seismic sensors using advanced ultralow-noise single-frequency lasers are presented. We have developed a family of vibration sensors that are based on extrinsic optical Fabry-Perot cavities, and provide many advantages compared with other types of sensors, including conventional fiber sensors and electromagnetic sensors. These novel sensors offer substantial reduction in size and cost, while still providing competitive performance. Size reduction also means an effective reduction in deployment cost, which is very important in the remote areas where seismic sensor arrays are needed.
