Beschreibung
Zusammenfassung:	The invention relates to a system (1) for detecting motion of a body (2) comprising a first elongated grating strip (4) coupled to said body and a separate and substantially stationary second elongated grating strip (5) crossing said first elongated grating strip. The system further comprises optical detection means (6) arranged to receive one or more light beams diffracted at said first and second elongated grating strips to detect motion of said body. The invention further relates to a method for detecting motion of a body (2) and to a body processing or inspection system. L'invention concerne un système (1) de détection du mouvement d'un corps (2) comprenant une première bande gravée allongée (4) couplée audit corps et une seconde bande gravée allongée (5) séparée et sensiblement stationnaire croisant la première bande gravée allongée. Le système comprend également un moyen de détection optique (6) destiné à recevoir un ou plusieurs faisceaux lumineux de diffraction au niveau desdites première et seconde bande gravées allongées pour détecter le mouvement dudit corps. L'invention concerne également un procédé de détection du mouvement d'un corps (2) et un système de traitement ou de contrôle d'un corps.
