Abstract
Et optisk spørresystem 10 omfatter et optisk forsterkende og signalutvelgende middel, i form av en halvleder optisk forsterker (SOA) 14 og en optisk kilde 12, 14. Driftsmidler 22 (en elektrisk pulsgenerator drevet av en variabel frekvensoscillator) er anordnet til å generere elektriske driftpulser (se innsatt (a)) som er anvendt på SOA'en 14 for å slå på og av SOA'en 14. Den optiske kilden omfatter en super-lysemitterende diode (SLD) 12, den kontinuerlige bølgeutgangen fra hvilken portes inn i optiske pulser av SOA'en 14. SOA'en 14 er optisk koblet til bølgelederen 16 som inneholder en matrise av reflekterende optiske elementer (gitre G) som skal spørres. Spørresystemet omfatter videre optiske detekteringsmidler 18, optisk koblet til SOA'en 14, som kan evaluere bølgelengden til en returnert optisk puls overført av SOA'en 14.
