Zusammenfassung:	PCT No. PCT/GB92/00811 Sec. 371 Date Jan. 14, 1994 Sec. 102(e) Date Jan. 14, 1994 PCT Filed May 5, 1992 PCT Pub. No. WO92/19936 PCT Pub. Date Nov. 12, 1992.A known method of measuring angular displacement of a shaft (11) using an optical grating mounted for rotation with the shaft is applied at two or more angularly spaced locations (16, 17 and 18) and the resulting measurements are process to produce a measurement of relative displacement of the shaft in a direction transverse to the shaft. Two locations are needed to measure displacement in a given direction. Three or more locations are necessary to provide full information about the displacement of the shaft.
