Zusammenfassung:A transparent window (2) covers the field of vision (15) of the optical apparatus (10). The window is movable for cleaning, and is rotated by a motor (8). The window is cleaned by a tubular ramp (20), parallel to the field of vision, with orifices (21) and flat jets (22) directed towards the window, and a fixed wiper blade (30). A pump (23) supplies cleaning liquid to the orifices. The ramp and orifices are located in a sealed chamber (24) having a semi-circular gutter (45) connected to a pipe (46) for liquid emptying. ADVANTAGE - Enables cleaning of optical protection window without obstructing the optical field of vision. Le dispositif (1) vise à protéger un appareillage optique (10) des salissures et des chocs. Il comprend une fenêtre transparente (2), par exemple en forme de cylindre creux, disposée pour couvrir le champ de vision de l'appareillage optique (10) et des moyens de nettoyage (20, 21, 27, 28, 30) disposés en dehors dudit champ de vision. La fenêtre (2) est mobile de manière à pouvoir être nettoyée par les moyens de nettoyage. Utilisation notamment pour protéger les systèmes d'identification et de détermination automatique des catégories de véhicule en particulier aux péages autoroutiers.
