Abstract
A method for determining the position of a first part moving in relation to a second part in a system, comprising forming a code on a surface of the first part or the second part, yielding an encoded surface; detecting the code on the encoded surface; decoding the code; and determining the position of the moving part from the decoding of the code; the code comprises microstructures at precisely selected positions on the surface of the encoded part; detecting the code comprises scanning the encoded surface with a sensor in conditions selected in relation to the code formed and to the encoded surface to precisely read the code on the encoded surface.
