An optical sensor for measuring physical magnitudes, such as a differential pressure, is described. The pressure sensor comprises a deformable diaphragm (24) which separates two measurement chambers (26,28) where pressures P1 and P2 exist. An optical conductor (34) is attached to the diaphragm (24)....http://www.google.fr/patents/US4899046?utm_source=gb-gplus-shareBrevet US4899046 - Optical sensor of physical magnitude
