Distributed optical fiber sensing (DOFS) has drawn a lot of attention in the geoscience community, taking advantage of easy-to-deploy, dense-spacing, and multi-physical measurements (temperature and strain), In contrast with traditional sensors, the optical fiber itself is. More time and cost effective deployment is possible, but continued research and development efforts are necessary to. AP Sensing was founded on the heritage of HP (Hewlett-Packard), the market leader in fiber optic testing and measurement for over 40 years. Fiber optic gyroscopes are a good and relatively inexpensive alternative to a laser gyroscope with a solid perimeter.
