Abstract
En optisk kilde (11) utsender en kildes optisk signal (12) som har en kildes optiske slgnals effekt og en bølgelengde. En splitter (14) eller annen tilsvarende anordning splitter kildens optiske signal l et første optisk signal (15) som har et første optisk signals effekt og et andre optisk signal (17) som har et andre optisk slgnals effekt, slik at kildens optiske signals effekt splittes mellom det første, optiske signalets effekt og det andre optiske signalets effekt. Denne splitting er avhengig av bølgelengden for kildens optiske signal(11). En første detektor (21) detekterer det første optiske signalets effekt og en andre detektor (22) detekterer det andre optiske signalets effekt. En styreenhet (25) reagerer på nevnte første (21) og andre (22) detektorer for å styre bølgelengden for kildens optiske signal.
