Abstract
The invention concerns a dynamic sensor for sensing the distance and the position of a surface moving past said sensor, including: a send optical channel (3) emitting radiation (4) towards the surface (1) and two receive optical channels (5, 6) each receiving a portion (4A, 4B) of the radiation (4) reflected or diffusely reflected by said surface (1); a radiation emitter (2) coupled to the other end of the send optical channel (3); an opto-electronic converter (7, 8) coupled to the other end of each of the two receive optical channels (5, 6); a processor device (9) connected to the opto-electronic converters (7, 8); in accordance with the invention: the send optical channel (3) and the receive optical channels (5, 6) respectively have a send axis (3A) and receive axes (5A, 6A) that are parallel to each other; the ends of the optical channels (3, 5, 6) facing the surface (1) are in a common plane perpendicular to the axes (3A, 5A, 6A) of the optical channels (3, 5, 6), each of said ends constituting the vertex of a triangle in said plane, one side of the triangle running from the end of the send optical channel (3) having a length different than the length of the other side running from the end of the send optical channel (3).
