1. A method for determining the position of one of two components in relative motion, with respect to each other, using optical means and comprising:
- directing at least one light beam emitted by a light source attached to a component towards a diffractive support attached to the second component, calculated and manufactured in order to generate an optical signal indicative of the positioning of said support, the optical signal being produced by the diffractive support in transmission and/or in reflection;
detecting and reading at least one optical code formed by said signal, which corresponds to a unique position of the diffractive support relatively to the beam;
assigning a position to each detected optical code; and
outputting the position to a user;
wherein each detected and read optical code is compared with electronic codes stored in a memory table for determining the position of the diffractive support; and
wherein each optical code corresponding to a position of the diffractive support includes at least one optical synchronization structure, the detection of which allowing the triggering of the reading phase of the optical signal integrating the code of a position of the diffractive support relatively to the beam.

15. A method for calculating the position of a component with respect to another one from an optical code formed by a photon signal generated by a diffractive support, said signal generating a code consisting of optical structures with variable intensity, distributed over detection means, comprising:
-
detecting the status of each optical structure and assigning it an electronic state corresponding to its intensity; calculating the value of the code of the measured position; converting said code into a distance; and outputting the distance to a user; wherein each optical code is compared with electronic codes stored in a memory table for determining the position of the diffractive support; and wherein each optical code corresponding to a position of the diffractive support includes at least one optical synchronization structure, the detection of which allowing the triggering of the reading phase of the optical signal integrating the code of a position of the diffractive support relatively to the beam.
