Paper Abstract

This paper reports how to choose the modulation frequencies of a time domain multiplexed optical fiber sensor network in order to obtain accurate measurement of the sensors' transmission factor. The signals are obtained by the interrogation method of distributed optical sensors with a multiplex of several modulation frequencies. Using simulation programs, the influence of the different system parameters was investigated. Shift invariance can be obtained with an IQ detector instead of the single real synchronous detector.
