    摘要: The present invention concerns a method for constructing a light coupling system wherein a grating is manufactured on the surface of a multimode waveguide and defines the entrance of the waveguide for an incident light beam, said grating comprising a repetition of patterns. The grating is defined by a set of parameters comprising: • grating period (P), separating two adjacent patterns, • grating depth (d) between the highest and the lowest point of the pattern, • incident angle mean value (θ) of the incident light with respect to the waveguide. The method comprises a step of optimization of the set of parameters to obtain an optimized second set of parameters, in order to obtain a transmission efficiency (Ce) of the incident light into said waveguide for the first or the second diffractive order exceeding 35% for unpolarized light, or exceeding 50% for polarized light, at a given wavelength of the incident light.

    摘要: The present invention concerns a method for working out the angular position of a rotating element which is mounted in a fixed frame, consisting in using at least one light source emitting a beam of light in the direction of a fixed sensor and using computing means for processing an output signal of the sensor,
    characterized in that it consists in:
    - a) arranging the light source with respect to the rotating element and of the sensor in a way so as to induce an interaction between the beam of light and the sensor which depends on the angular position of the rotating shaft,
    - b) arranging on the path of the beam of light, in a fixed position with respect to the sensor, a perforated mask which presents a repetitive pattern of perforations,
    - c) detecting shadows generated by the mask on the sensor,
    - d) processing the output signal of the sensor for determining the position of the shadows on the sensor,
    - e) and computing the angular position of the rotating element by using the position of the shadows.
