An angular rate sensor for measuring angular velocity about a cavity sensitive axis which includes a fluid filled cavity, means to cause rotation of the fluid in the cavity about an axis perpendicular to said sensitive axis, the fluid having parallel to said rotation axis a flow rate gradient, and means to sense a change in the flow rate grandient with rotation of the cavity about said sensitive axis. The means can be electrical, as by measuring the change in electrical potential or electrical resistance or electrical current across the flow path, or optical by measuring the change in distribution of a neutrally buoyant material in an optically transparent fluid. |
