Abstract

SISTEMA DI COMUNICAZIONE OTTICA COERENTE CON VARIAZIONE CONTINUA DELLA POLARIZZAZIONE, IN CUI TALE VARIAZIONE E' OTTENUTA SOVRAPPONENDO RADIAZIONI A FREQUENZA DIVERSA POLARIZZATE ORTOGONALMENTE, EMESSE DA DUE SORGENTI INDIPENDENTI (1, 2; 201, 202). LE DUE SORGENTI POSSONO ESSERE IMPIEGATE PER REALIZZARE IL TRASMETTITORE O L'OSCILLATORE LOCALE DEL SISTEMA (FIG. 1).
