The system includes a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector, each including a light source for illuminating the reflector, and a light detector for receiving the light reflected on the reflector and for generating an electrical signal representative of the reflected light. A processor processes the electrical signals, and determines a parameter relating to the angular movement of the arbor. The rotating reflector is a cylinder of revolution and light absorption points are made on the circumference of an external cylindrical surface. When the reflector rotates in a regular manner and in the same direction of rotation, the representative electrical signal generated by each detector has a sinusoidal shape.

Abstract: A layer of lanthanum boride of stoichiometry LaBx where x is between 9 and 12 is deposited on substrate, for example a stainless steel watch dial, and subsequently treated with a laser, such that the portion(s) of the layer treated with the laser change colour according to the laser power. This produces multicoloured surfaces having high resistance to corrosion and abrasion. The layer of LaBx is deposited by PVD and by cathode sputtering, using a LaB6 target of purple-violet colour, such that the colour of the deposited layer differs from the colour of the target. The laser treatment at specific powers changes the stoichiometry of the layer in the treatment portions, such that the colour of these portions changes according to the stoichiometry obtained. At higher powers, the laser will remove the layer of LaBx. Thus the colour of the treated portions is determined by the material of the substrate.
