ABSTRACT:
A system for measuring angular displacement of a shaft 11 using a sensor pick-up mounted for rotation with the shaft at two or more angularly spaced locations 16, 17 and 18 wherein the resulting position measurements are processed to produce a measurement of relative displacement of the shaft in a direction transverse to the shaft, two locations being needed to measure displacement in a given direction, and three or more locations being necessary to provide full information about the displacement of the shaft.
