Abstract :
This paper presents an analysis of an analogue correlator used in direct sequence, spread spectrum multiplexed, fibre optic sensor networks, in addition to detailing the low frequency coupling requirements of the system. It is shown that the form of the post-multiplier filter impacts upon both the measurand bandwidth and the cross-talk performance between the sensors. Experimental verification of this theory is also reported
