Abstract
The device includes an incremental optical encoder (3) comprising two parts, 4,5) which are displaceable in rotation within one another. One part (5) is associated with a movable component (1) and the other part (4) with a fixed component (2) and its output is connected to a device for determining the angular position of the movable component (1) relative to the fixed component (2) on the basis of the relative angular positions of the two encoder parts. The encoder (3) is carried by one of the components (1), and one if its parts (5) is connected to this component (1) while the other part (4) is connected to an optical device for slaving the encoder part in at least one specified orientation in relation to the other component (2).
