Abstract (en)
[origin: WO2008056383A1] An industrial machine (200) is described comprising: - a moving structural element (2) for adopting different positions in corresponding operating configurations of the machine (200); optoelectronic measuring means (11, 12) of a distance (d) between a first reference axis (al) and a second reference axis (a2) associated to said structural element (2); characterized in that said optoelectronic measuring means (11, 12) comprise a laser interferometer (20) and a measuring reflecting target (12) that are optically coupled to each other and each being associated with one of said reference axes, said laser interferometer including a laser source for emitting a direct electromagnetic radiation to said target (12) and interference means between a reflected electromagnetic radiation from said target and a reference electromagnetic radiation obtained from the direct electromagnetic radiation.
