Abstract

A gravity gradiometer having quadrupole responders in which a mass quadrupole is supported by a torsional spring forming a flexure allowing rotation of the mass quadrupole about its center of mass. The flexure can be a pair of spaced apart posts. The flexure can be made from glassy metal having at room temperature a high elastic limit, high stiffness, high strength and low internal damping. The flexure can alternatively be a web made of glassy metal.
