<p>The system has a fixed electro-optical device comprising a point-like emission source (S) i.e. laser source, which is collimated by an optical lens (L). The emission source and a photosensitive detection assembly i.e. photodetector, are symmetrically arranged with respect to a semi-reflecting optical element (m). Cube corners (C1-C3) form an interferometer by interference of a part of light coming from the collimated source with another part of the light on the detection assembly depending on an orientation of an axis that joins two centers of the cube corners.</p> |
