INTERFEROMETRO CON TRASMISSIONE IN FIBRA OTTICA DELL'INFORMAZIONE DI FASE UTILE.

摘要

The invention relates to an inerferometer based on the exploitation of an optical fibre through which both the phase signal which is of interest for the measurements concerned and a reference signal are simultaneously forwarded in order that in the differential measurement the noise introduced by the optical fibre for both thermal and mechanical reasons is ruled out.
