Highlights • High-Ti lavas have the same composition as Walvis Ridge and Gough Subtrack. • Low-Ti lavas are derived from a distinct source compare to the high-Ti lavas. • High-Ti and low-Ti basalts reflect the spatial zonation of the plume head

In this paper, we propose a new type of push-pull structure fiber optic accelerometer based on 3×3 coupler for the first time and carried out measurements of its responsivity and cross-axis sensitivity. With specific algorithm, the phase signal of t

Considering the negative relationship between the production of gas and water, we should minimise water production. The dip angle of hydraulic fracturing can control not only the hydraulic connectivity between the roof and floor aquifers and the coal

A novel all-metal fiber-optic accelerometer with Michelson interferometric configuration is proposed, using mass blocks and flexible reed structure. The sensing arm is configured to directly transform the applied acceleration to fiber deformation in

Pressure phase sensitivity is one of the most important performance indexes of the fiber-optic hydrophone. Maximizing the pressure phase sensitivity is a basic principle in the fiber-optic hydrophone design. In this work, the orthogonal experimental

In this work, the acceleration responsivity of the optical-fiber air-backed mandrel hydrophone is proposed and investigated both analytically and experimentally. The acceleration responsivity is a significant index of the hydrophone, and it would be

A 3-Component fiber-optic accelerometer (FOA) array used in oil-well logging is presented. A novel and general parameter (SB2D-1P) to evaluate the characteristics of the interferometric FOA is brought forward
