Abstract
The invention relates to an angle measurement probe on board an aircraft, which comprises a fin, which can move in rotation about an axis, at least one first optical encoder and one second optical encoder, each comprising at least one disk, each disk being fixed at right angles to the central axis and being provided with at least two circular tracks, each track being provided with alternate opaque and transparent zones, means for processing the output signal from each encoder.
