ABSTRACT:
An accelerometer has a tubular coil that surrounds coaxially a cylindrical magnet. The magnet is polarized along a second axis transversely of the common axis of the coil and magnet. A sleeve of soft-iron surrounds the magnet and coil to provide a magnetic return path, the sleeve having two vertical slots which receive bearings. The bearings are carried by a shaft that extends across and above one end of the coil so that the coil is supported for angular displacement about a third axis orthogonal with the common axis and the second axis and displaced from the second axis. An optical pick-off mounted below the other end of the coil is used to sense rotation about the third axis, by detecting displacement of a portion of the former on which the coil is wound.
