Abstract
The present invention relates to a device 3 for protecting an optical sensor 13 for an automotive vehicle that is intended to be attached to the optical sensor, characterized in that the device includes:—a transparent optical element 9 exhibiting rotational symmetry and being rotatably mounted about an axis of rotation, configured to be positioned upstream of the optical sensor 13 so that the axis of rotation of the optical element 9 is merged with the optical axis 15 of the optical sensor 13; and—an actuator 5 that is coupled to the optical element 9 so as to rotate the optical element 9 in order to allow soiling to be removed by a centrifugal effect.
