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
An optical interrogation system 10 comprises an optical amplifying and signal selecting means, in the form of a semiconductor optical amplifier (SOA) 14 and an optical source 12, 14. Operating means 22 (an electric pulse generator driven by a variable frequency oscillator) are arranged to generate electric operating pulses (see insert (a)) applied to the SOA 14 to turn the SOA 14 on and off. of the SOA 14. The SOA 14 is optically connected to the waveguide 16 which contains a matrix of reflecting optical elements (gratings G) to be interrogated. The interrogation system further comprises optical detection means 18, optically coupled to the SOA 14, which can evaluate the wavelength of a returned optical pulse transmitted by the SOA 14.
