摘要： A Ferraris sensor for measuring an acceleration of a moving body along a direction. The sensor includes a flat eddy current body and a scanning head arranged on one side of the eddy current body. The scanning head includes N magnets that generate an external magnetic field that extends approximately perpendicular to a surface of the eddy current body, wherein Nnull1, 2, 3, . . . and M detector coils, wherein Mnull1, 2, 3, 4, . . . and each detector coil includes an axis and detects changes of an interior magnetic field within the N magnets that are caused by an acceleration of the eddy current body and a resulting change in eddy currents. The axis is approximately perpendicular with respect to the surface of the eddy current body, each detector coil lacks a ferromagnetic core and the N magnets and the M detector coils are arranged alternatingly next to each other in a direction that the acceleration is to be measured.

摘要： The present invention is a seismometer/velocimeter, and can be also made to function as an accelerometer. The invention comprises an in-plane suspension geometry combined with a transverse periodic-sensing-array position transducer. The invention can incorporate a feedback actuator of magnetic design, incorporating fixed magnets and planar coils on the surface of the proof mass allowing for much lower noise than an equivalent electrostatic actuator without requiring high voltages. The invention may also have a dual-axis configuration by using two sets of springs. The nested suspensions allow the proof mass to move in two orthogonal directions. A three-axis configuration is possible by combining the dual-axis version with sensing and actuation of the proof mass motion out of the plane. The position sensing for the out-of-plane motion can be made using schemes common in existing state-of-the-art sensors. Actuation for the sensors may be electrostatic or electromagnetic in each of the axis.
