7.1  PRINCIPLE OF AC-OFCS AND EW-OFCS

An optical fiber chemical sensor (OFCS) detects the existence of and measures the concentration of a compound in a sample through detecting the interaction of the compound with light propagating inside an optical fiber. 1,2 Depending on the location at which ...
