Abstract
The measurement method of the displacement speed of a moving element with respect to a fixed element is performed by means of an optic measuring device comprising a first reference sensor and a plurality of distinct second measurement sensors substantially aligned along the axis of movement of the moving element. The measurement method comprises determination of estimated speeds by correlation of the signals supplied by the reference sensor and each of the measurement sensors, and calculation of a mean speed of said estimated speeds.
