ABSTRACT:
A method for determining the position of one of two components in relative motion with respect to each other, using optical means, comprises:directing at least one light beam emitted by a light source attached to one component towards a diffractive support attached to the second component, calculated and manufactured for generating 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, and the optical signal including information indicative of its quality;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; andassigning a position to each detected optical code.
