Abstract:
THis Paper derscribes a novel all-fiber compensation network with three access-couplers for improving the stability of amplitude modulated fiber optical sensors. and its optimumstructure which is indepent on environment effects. We also describe the sealing method of the com-pensation network and the experiment of its coupler parameter variation caused by tempertare andvibration. The expreiment results showed that the compe nsation network can effectivelv resist themeasurement error affected by the in tensity variation of the optieal souce and other transmission loss.
